Here are some text-related hotkeys. Sorry if this is well-known stuff, but if it helps just one person it's worth it. They work in most windows editors, and some others too (sublime text on linux, etc). They work in visual studio, notepad++, etc etc.
basic stuff: please do not right click to copy, paste, etc. This is horrible

you kill babies every time you do it. There are hotkeys for those operations. In fact, using the mouse when editing text is way too slow 99% of the time. There are occasions where it'll be faster, but they're not the majority.
If you hold shift, moving the cursor will highlight text. This is usually faster than moving your hand to the mouse to highlight text, especially combined with some extra hotkeys below. Shift+up to highlight from your cursor to the line above, etc.
In most editors, you can indent multiple lines at once by highlighting some text on each line and pressing tab. For example, hold shift and press up 3 times. Then press tab. This should indent the line you started on, plus the 3 lines above it. You can un-indent with shift+tab.
Most editors have a hotkey for commenting out any lines you have highlighted. Often it involves ctrl+k.
ctrl+arrows moves the cursor by word instead of by character. If you want to highlight a word before your cursor, press ctrl-shift-left. Done.
Using ctrl to modify the way you move around the cursor will change your life.
Similarly,
ctrl+delete and
ctrl+backspace will get rid of a single word.
Use the
home and
end keys a lot. Like, all the time. Don't hold the right arrow key to move to the end of a line, just press end. If you need to highlight the whole line you're on, press home, then shift+end. Also, home will alternate between the very beginning of the line and the beginning of the indented text.
There's usually a hotkey for cutting an entire line. It's
ctrl+L in most things I've tried, but sometimes ctrl+K.
In visual studio ctrl+W will select the word around your cursor, which can be useful sometimes. But in most other places that will the child window / tab.
ctrl+home and
ctrl+end will go to the very beginning or very end of a document. So naturally, ctrl+shift+end will highlight all the text after your cursor until the end of the document.
Most good editors have an amazing feature called multi-line editing. You can expand your cursor to cover multiple lines and edit on all of them at the same time. Often times this is the hotkey
alt+shift+up/down.
