I used to be a very heavy AHK user and developed a rather extensive config. Here is my config along with a boilerplate to help you start one that is similar:

- https://github.com/denolfe/AutoHotkey

- https://github.com/denolfe/AutoHotkeyBoilerplate

Use official forum, it has tone of good examples.

Here is something I did long time ago: https://github.com/majkinetor/mm-autohotkey

this one saved me a lot of time over the years. not a 100 hours but its definitely something i could use maybe a hundred times a day.

basically when you want to search something, just highlight the word(s), press a hotkey then select a site from the list and it will open up the page directly
