How can I increase the key repeat rate beyond the OS's limit?

Question

I have a bad habit of using the cursor keys of my keyboard to navigate source code. It\'s something I\'ve done for 15 years and this of course means that my navigating speed is

Answer 1

Well, it might be obvious, but:

• For horizontal navigation, Home (line start), End (line end), Ctrl-Left (word left), Ctrl-Right (word right) work in all editors I know

• For vertical navigation, Page Up, Page Down, Ctrl-Home (text start), Ctrl-End (text end) do too

Also (on a side note), I would like to force my Backspace and Delete keys to non-repeat, so that the only way to delete (or replace) text would be to first mark it, then delete it (or type the replacement text).
