AutoHotKey - Control Your Mouse With Your Keyboard

     A month ago I bought a 40% keyboard. Some people might be wondering what a 40% keyboard is, it is just what you would think it is, it is 40% of the size of the standard 105 key layout. All the keys that have been removed are now stored in programmable layers. so for instance to make an exclamation mark I have to hold down, Fn1 + right shift + Capslock, this might seem insane but it is actually very intuitive after a week or so and now that I have fully adjusted I can hit any key without moving my fingers from the home row. Good-bye wrist pain!

To be completely honest I did not think I would like using a 40% keyboard, especially as a daily driver. But after a week or two I found myself enjoying typing like seriously, typing is now fun and enjoyable.

Alright now that we have gotten that out of the way, the point of this post is to share an AutoHotKey script that I have been running which allows me to control my mouse without actually having a mouse!

This script was developed using the AutoHotKey programming language and was aimed towards a 40% keyboard but with some slight modifications, it can work on any keyboard. Please review the comments and adjust accordingly for a full-size keyboard.

Here's the script in all its glory!
; MouseControl.ahk
; Hold down Control and then use the arrow keys to move the mouse cursor around the screen

#Persistent ; Keeps the script permanently running (that is, until the user closes it or ExitApp is encountered)

y := (d-u) * distance ; math to tell how far to move the cursor
x := (r-l) * distance ; more math to define how far the cursor moves per key press

MouseMove, x, y, , R ; Initiates the action of moving the mouse

^PgUp::Click,      left  ; Sets Ctrl + PgUp to perform a left click
^Esc::Click,       left  ; Sets Ctrl + Escape to perform a left click
^r::Reload  ; Assign Ctrl-R as a hotkey to restart the script.
Return ; End of Function statement

 I hope you enjoy it as much as I do! Any questions, just ask!
