Suggested short-cuts for "Command" shortcuts used across most programs

Question

I often find myself using the following no matter what the program is:

• Cmd s to save.
• Cmd a to select-all
• Cmd t to open a new tab
• Cmd c to copy
• Cmd v to paste
• Cmd z to undo
• Cmd Shift z to redo

That how it works in most computers, regardless of what mode I'm in or whatever. What would be a good keyboard mapping I can use in vim to do something similar? I don't believe cmd is supposed (without doing some odd mapping).

I also am not a big fan of using ctrl as I often use that in other programs to advance to the start of a line ctrl a or advance to the end of the line ctrl e, and I'm already familiar with ctrl v for visual mode.

What might be a good mapping where I can do something that might feel close to doing the cmd-letter input, i.e. and it will work across all modes (that is, I should be able to select-all whether I'm in normal mode or insert mode)? Additionally, if useful, I'm using vim on mac and (mainly) ubuntu.

Answer 1

I would suggest installing MacVim which already comes with many (all?) of these keybindings set as default.

Within MacVim, I found I could use <D-key> in mappings, to capture Cmd-key presses.

For example:

# Undo and redo
nnoremap <D-Z> u
nnoremap <D-S-Z> <C-R>
# Navigate back and forwards
nnoremap <D-[> <C-O>
nnoremap <D-]> <C-I>

I don't know if these will work for vim in a terminal. They might.
