The tab key makes you go to end of document is the only issue, otherwise well made.
The following autohotkey script fixes the issue for Windows users by intercepting the tab key, preserving your clipboard, putting tab into your clipboard, pressing control-v, then restoring your clipboard.
The word "docs" has to be in the active window title, otherwise it wont intercept your tab key, so you should be able to leave this script running at all times.
Install autohotkey, then put the below text into a text file and rename the file extension to .ahk and double click it.
temp = %clipboard%
clipboard = %A_Tab%
clipboard = %temp%
