Customized Vertical Cursor Movement

This NeoVim configuration includes a customized vertical cursor movement tailored for Colemak users. It can be located in cursor.vim, and it serves as an alternative to the "number + up/down" key combination.

In order to move the cursor up x lines, press the [ key, and treat the middle row of the Colemak keyboard layout ("arstdhneio") as number 1 to 0. Press the numbers that you'd like your cursor to move (x) and press the space bar.

To move the cursor down, press the ' key instead of the [ key, and the rest would be the same.

Example: | Shortcut | Action | |-------------------------|--------------------------------| | [ a o o SPACE | Move the cursor up 100 lines | | ' a r s SPACE | Move the cursor down 123 lines | | [ d o SPACE | Move the cursor up 50 lines |

Note: As of now, you may only move vertically up to 199 lines with this key configuration!
