I actually unbind ctrl+g because I hit it a lot when I'm going for ctrl+f. ctrl+c cancels out of it fine.
For most stuff I just use autosuggestions.
I disable the caps LOCK FOR SAME REASON.
I make caps lock a ctrl key.
Yeah, pretty much the only ctrl key I use.
I use ctrl-c a lot in the terminal.
Yeah, in terminal I use a lot of ctrl+c,d,f,p,a,e,h,w,k
I use a lot of them shell shortcuts -_-
Ctrl+1 (to8) in a browser to switch between first 8 tabs.
Ctrl+9 to go to the last/furthest right tab.
Also, ctrl is the hack workaround for the infamous one-button mouse.
Win+x, u u to quickly shutdown Windows. Although I've done this lots of times and not realised Notepad was open and my laptop has been on in my bag all night (my work one stays on when the lid is closed).
Not a keyboard shortcut but you can customise Explorer so it defaults to starting at This PC.
