Entering visual mode if user press "ctrl+a" to select all lines

[zyucan]

currently, I use ctrl+a to select all lines, but vim is still in normal mode, if I select all lines using mouse, then vim enters visual mode as I expect.

You could do something like gg+ctrl-q+G to select all the text, is used to increase numerical values, you could remap the gg, then ctrl-q, then G to something more comfortable, with a leader key combination.
