How to bind <A-,> and <A-.>

Question

Trying to bind <A-,> and <A-.> to tabprevious and tabnext respectively.
What's the correct syntax for Alt bindings?
<A->?
<m->?

Thank you

I can map <a-j> and <a-k> so that works but I'd wonder how to map , and .

Answer 1

The list of supported special sequences is available in the documentation here and <a-.> or <a-,> aren't present there. However, typically Alt-combinations are Esc followed by a character, so just <esc>, and <esc>. should work.
