how i can add a custom short-key?

I’m asking to learn how i can add a short-key. (hot-key)
For example when i press the “Ctrl + {”
to do something that i want so i’ll not waste time.

edit: when i said “short-keys” i was meaning “hot-keys”.

File > User Preference > Input > Good Luck :wink:

tips, use the search bar to find the tools you want.

Most keys you can actually rightclick and simply “add shortcut”. but you can find Everything in the user preference.

Thanks for your answer!
