Re: how to set a map for toggle _ and =?

In this particular case, the easier way to proceed is the following.

First, you need the actual mapping:
:nnoremap <expr> _ (g:maximize_or_equalize ? ":wincmd_\<cr>" : ":wincmd=\<cr>")

Then, some way to toggle the variable g:maximize_or_equalize:
:let g:maximize_or_equalize=0
:nnoremap <leader>_ :let g:maximize_or_equalize=1-g:maximize_or_equalize<cr>




However, as I always use gvim, I tend to prefer relying on a more "standardized" (as in: "every thing works this way on my systems) way to toggle g:maximize_or_equalize:
:call lh#menu#def_toggle_item({
\ "variable": "maximize_or_equalize",
\ "values": [0,1],
\ "menu":{"priority":"70.900", "name": "Window.Reorganize"},
\ "texts": ["maximize", "equalize"]})

Which automatically provides the command:
:Toggle WindowReorganize
and updates the menus to display the current option.

NB: this is a shameless advertisement of a vim librayry I'm maintaining: http://code.google.com/p/lh-vim/wiki/lhVimLib
