I don't know where any documentation would be, but for now, here are some shortcuts:

ctrl+/: Comment out highlighted lines of code (// example)

ctrl+shift+/: Block comment highlighted text (/*example*/)

ctrl+z, ctrl+y: Undo and redo, respectively

ctrl+f: Search for text in code

ctrl+f twice: Replace instances of text with different text

ctrl+s: Save project

ctrl+[, ctrl+]: Decrease and increase indent of highlighted lines, respectively

ctrl+k: Jump carat to next instance of highlighted text

Arrow keys: Move carat around

ctrl+UP, ctrl+DOWN: Scroll up/down in code

ctrl+LEFT, ctrl+RIGHT: Move carat to next punctuation/whitespace/line

shift+arrows: Highlight text while moving carat

ctrl+shift+arrows: Highlight text while moving carat, moving to next punctuation/whitespace/line

ctrl+shift+UP, ctrl+shift+DOWN while carat is to the RIGHT of any digit: Increase or decrease digit to the left of carat by +1 or -1

The above are all shortcuts that I regularly use in my coding. Because of these I rarely use my mouse, only using it to focus on the canvas instead of the code. The last shortcut is the one I probably use the most -- it really saves time spent retyping a bunch of numbers, and makes it much easier to make values what you want them to be. You can increment by any multiple of 10 depending on where you put the carat. Funny enough, I didn't know about the ctrl+k thing... that means that there are probably more shortcuts out there...

Exactly. Thanks for responding. I already knew most of these, but one I didn't know was the number incrementation, which will be super helpful as you already said. Even better might be the indentation, which I usually have so much trouble with if I pasted something in from elsewhere.

Yeah, I just found ctrl+k a few days ago when I was searching for a way to delete a whole line at once, and apparently ctrl+k is what some sites use for that. One that you didn't mention here, and so might not know, is one I find quite handy...

ctrl+alt+0: Collapse all collapsible blocks
