These are some small scripts to create hotkeys for small tasks (such as encoding decoding).
git clone https://github.com/meispi/shortcuts
create a batch script (.bat file) with these instructions
@echo off
python your\path\to\shortcuts\base64encode.py
create a shortcut of this .bat file in the same directory as the .bat file
go to properties of the shortcut file and write your hot key for this task by pressing those keys in the shortcut section
then click apply
