vim key mapping reference

Question

I've just installed the command-t plugin and what to map it to cmd-t instead of leader-t. I'm fairly new to vim and I don't know what the symbols are for the key mappings. Where can I find a reference for the symbols you use when mapping key combos in vim?

Answer 1

a vim principle is that an undocumented feature is a useless feature. So vim documentation is all you need.

:help :map
:help :map-special-keys
