unmapping in Vim

Question

I am in the habit of using both querty and dvorak keyboard mappings on my computer, and would like to make a function in vim, that remaps h to d, j to h, k to t, and l to n. I would also like a function that would switch the mappings back. I can handle the forward function, but am at a loss as to how I would unmap the previously defined mappings.

Answer 1

Vim dvorak users may be interested in this wiki page that tells you how to use dvorak in insert mode while keeping the command keys the same in normal mode:

Also, the (i|n|x|etc.)unmap commands unmap.
