<C-a> works ok for me, number is incremented. But
<C-z> does not decrement. Instead gvim window is minimized to be background.
How can I disable that
<C-z> behaviour and have it increment numbers?
I am using Gvim 7.4 on windows 7 64its and not using mswin.vim. I just source a copy of it with most stuff disabled, only minimal mappings.
<C-z> does not exist in my custom mswin.vim.
