By the way, recently discovered you can get some of these shortcuts in all input boxes by activating “emacs shortcuts” inside of gnome-tweaks! Was one of the final blockers for getting me from Mac to Linux
You can also use the more standard Home/End/Ctrl+Left/Ctrl+Right to do all of the above. Much easier to remember and works in any other editor also.
!cmd = repeat last usage of that command
!!enter which is 3 buttons where as up-arrow enter is the same thing.

!! is more useful than you think. It's substitute last command here, not just up-arrow enter.
See sudo !!.

Yes! I use c-u to clear the line all the time.
<c-a> = go to beginning of line
<c-e> = go to end of line
!! = repeat last command
<esc> b = move "back" one word (also <c-b> and <c-left>)
<esc> f = move "forward" one word (also <c-f> and <c-right>)
Many others exist. See `man bash` under READLINE.
