Thumbs up for PJ.
Guys, look at the lower left corner of your keyboard. You should see four keys in a row - Z, X, C, V. And somewhere in the same corner there is a key marked CTRL. On my keyboard its right under my left little finger. These keys do the following UNDO, CUT, COPY, PASTE. These happen to be the four most used functions in most Windows programs. Not that hard to remember four basic keystrokes. Make up memory tricks like thinking that Z is the last letter in the alphabet, and CTRL-Z UNDOes your last step. X looks like scissors blades so CTRL-X cuts whatever is selected/highlighted. C is the first letter in COPY, so CTRL-C copies. V doesn't stand for anything except its the next closest key in the keyboard sequence so CTRL-V pastes. It is easy to use my left little finger to hit the CTRL key and hold it down while my left index finger hits Z, X, C, or V. Probably dozens of other program specific keyboard shortcuts but these four cover 90% of anything you need to do to edit text.
