The mysterious command prompt question

Hello

A while ago I was using the command prompt window but accidently press some buttons on the keyboard with my arm. I wasn't sure which button I press but all I know was I didn't hit any function keys or the enter button that executes the command.

I wondering is there any possible hotkey commands in the command prompt that can cause a executing changing the settings on my computer, or is pressing the enter button in command prompt the only way to execute something on my pc. Sorry for the dumb question and many thanks in advance. I'm just kinda worried since ppl say to be careful executing stuff with command prompt, I swear starting into that black window looks like the myterious void.

eep, I was running as admin earlier. Does it mean there's some commands that can change the settings on my computer through the hotkeys alone and not having to press the "enter" button...?

Do you mean it's impossible for command prompt to change anything on my PC as long as I never press the "enter" button?

Last month I've checked all the hotkey commands for W7 and other windows program, but they never mentioned anything for command prompt : /

phew... thanks, at least I'm much more relieved now. :)
