Setting up your Display

Your laptop or pc screen, comes all good to go on default. However there are a few things you can customize to your liking.

Set Refresh Rate/Resolution(external monitors)

External monitors can be advertised as 144hz and 4k, but they won’t actually run at said settings. You’ve got to change that.

Head in to Settings>System>Display. Under “Scale and Layout”, you can change your displays resolution.

To change the refresh rate, go under “Multiple Displays”. select advanced display settings.

Here you can select your specific display and set the proper refresh rate.

Saturation/RGB/Advanced settings.

More settings can be found in your graphics card’s control panel

Depending on if you run intel graphics, nvidia graphics, or amd graphics, this process will look different. However the main process is similar, if not exactly the same. I have an nvidia card, so I will be showing the process through Nvidia.

Right click any empty space on your desktop, and click “Nvidia Control Panel.”

For amd users, the software will be named “AMD Radeon Settings.”
For intel users, it’s “Intel Graphics Settings.”

Once Nvidia Control Panel has opened, on the left hand task bar you can see a dozen different tabs for you to navigate through for your display. The most important one here, is “Adjust Desktop Color settings”. Here, you can entirely change the way your display represents colours.

For Intel and AMD users the process is fairly similar. If you are still having trouble navigating through your system, or the software, click the following links.

How to use ShareX!

ShareX is a screenshot tool created to make taking screenshots more efficient. Another alternative is lightshot, however I believe ShareX is a greater tool with better personalization.


  1. Go to . You should be directed to a home page that looks like this.

2. Click the download button. A setup file should appear at the bottom of your browser.

The download button is located near the top. There is also a downloads sub-category if you would like to download previous versions!
Here’s the setup file.

3. Open the setup file by clicking the file, or right click and hit “open”.

4. You will now be prompted to go through the very simple installation process. Go through the steps instructed on the screen, and you’ll have ShareX downloaded in seconds!

Getting to know ShareX

ShareX should pop up on your screen. If not, it may be minimized in the background. To open the application, left click the arrow on the right of your taskbar. This should open your minimized application tray, where you’ll see ShareX.

There it is! Top row in the middle.

Right click the ShareX icon. You’ll see a tray pop up with many ready to go options such as screen shot, record, create gifs, and more. We’re going to click open main window.

Here’s the homepage for ShareX. In the middle, you can see some key hotkeys that can be used to do different things The most useful one in my opinion, is capture region.

Capture Region

Capture region allows you to select a portion of your screen to screenshot. That way, you don’t have to crop the picture later after you’ve taken it!

Screen Recording

Screen recording… is rather straight forward. ShareX will prompt you to select a portion of the screen you would like to record, and it will start recording! To stop recording, press the assigned hotkey again, or click the stop button underneath the region you are recording.

Screen Recording (GIF)

Recording a gif with ShareX works the exact same way as normal screen recording, except… it will be turned into a gif file.

After Capture Tasks

If you use ShareX and take a screenshot, there are a few things you can tell ShareX to do after you’ve taken the screenshot. To check out your options, on the side bar of the application you will see a subheader called After Capture tasks. Clicking it will open up this menu with a list of the many things you can tell ShareX to do after screenshotting.

Right now, I have Copy Image to Clipboard, and Save Image to File toggled on. This means ShareX will save my screenshot as a file within my screenshot folder, and it will also copy the image to my clipboard so that I can simply paste the picture wherever I want to share it!

After Upload Tasks

After taking a screenshot, video, or gif with ShareX, you can tell ShareX to upload the file to an online host. These hosts such as imgur, pastebin, streamable host your file so that you can share it easily with others. All you have to do is copy the link to your file on their site, and send it!

1. To do this, you’ll first want to start by sending your file to a host. Click the Destinations subheader on the sidebar. A menu will pop up with the current hosts that ShareX will send each type of file to. Change them as you wish!

If you want ShareX to upload the file to a host with your own account for that host, click on Destination Settings. EX: i want to upload to imgur with my imgur account, Im going to hit destination settings and log in to imgur from there!

2. After choosing your hosts, you want to go to After Upload Tasks in the sidebar and click Copy URL to clipboard. This copies the link to your file, on the hosts website.

There are also a few more options. Play around with them.

3. Now ShareX will upload any videos or files to the host, and copy the link. But it won’t work for images just yet. To get this to work with images, go to After Capture Tasks and hit Upload Image to Host.

By default, ShareX does not send an image to a host because the image will be on your computer regardless. That’s why you need to change it!

And these are the basics to ShareX. There’s a lot more in this program, so explore!

Creating Fillable PDF files!

  1. Go to We will be using the free online version today. I recommend making an account if you’d like to edit any fillable documents that you’ve already created.
Should look like this

2. Upload your PDF file

3. Once you’ve uploaded your file (I will be using a PDF file I was given earlier this year), it should look like this:

Creating Form Fields

There are a variety of different form fields you can choose from

TEXT: Ideal to use for short written fields such as “Name: “, “Age: “, “Email: “. Basically anywhere you only need to use one line for!

Click and drag on the page to insert new object

At the top, you will be able to see the font and size options. This is how the text that the user puts in will show up. I usually higher the font size to 15-17 depending on the text around it.

You can test out the text options by typing in the form field you just created

Right-click on a form field to find “Object Properties”. There will be more options.

TEXT PARAGRAPH: Self-explanatory title! Used for larger, multi-lined, form fields. Using the same steps we did for the TEXT tool we can get…

CHECKBOX: Also self-explanatory! Anywhere you’d like a checkbox, slap it on there. If you go to its object properties, you can customize the check type to different icons (such as stars!)

It will automatically show up checked, so I like to uncheck it before I finish.

Those are the only tools I’ve had to use when converting documents into fillable PDFs, however, there are more options such as dropdown and listbox (where the user can choose an option from several choices). You can edit the options/choices in the Object Properties.


The blue save icon is… well… the saving button, and the green button below it lets you download your beautiful creation 🙂

How to Import a Microsoft Word Document

Drag and drop a file from your computer to upload it to Google Drive

Even if you’re new to Google Docs, you might already have a collection of Microsoft Word files you’d like to be able to use. If that’s the case, then you’ll have to upload all your Word documents before you can view them. 

When you import a Word document, you can use either Google Docs or Drive to upload your files. Both methods let you drag and drop a file from your computer directly into the web browser for easy uploads. Google Drive stores all of your uploaded files when you head to the Docs homepage, it only shows you document-type files.

From the Google Docs homepage, click the folder icon in the top right, then click the “Upload” tab.

Once the Word file uploads, Docs opens it automatically, ready for you to start to edit, share, and collaborate.

To open a Word document that you want to edit, click the file with the blue ‘W’ next to the filename from your Google Docs homepage.

Click either view the Word file or edit it in Docs.

Choose to either View the Word file or edit it in Google Docs

When you finish with the document, you can download your document back into DOCX, or PDF, ODT, TXT, HTML, or EPUB format. Click File > Download As then click on the desired format, and it will download directly to where files save from your browser.

Click File, Download As, then choose a file type to download to your computer
