Keyboard-only column block selection in GVim Win32, or why does Ctrl-Q not emulate Ctrl-V when mswin.vim is included?

Question

I want to be able to select columnar blocks using only the keyboard when I use GVim on Windows, but I do not seem to be able to do so when using gvim (7.2) on Windows XP. E

Answer 1

One way to visually select column blocks in GVim on Win32 using only the keyboard is to press Ctrl-Q, release it, then press and hold down the Shift key while using the arrow keys to select the column block.

Why Ctrl-Q columnar selection behaves this way is not known, but it does not really matter since the goal was to select column blocks using only the keyboard. In Vim, Shift is not used when using Ctrl-V to select blocks.

:help mswin does not mention this nuance of the CTRL-V alternative.
