I have several scripts that make my keyboard behave better, which is "automating" in a sense. I basically have vim-style keys anywhere on the computer, as long as I'm holding caps lock. (So e.g. caps+j is the same as down arrow). This includes some more complex motions like "select current word", and even things like "open two quotes and but the cursor between them."

I also have a script which scrapes my podcast player's website, to give me a list of podcast episodes that I already played. I save this list every day in an excel file, but the script makes this much easier - I run the script, then paste the results into the excel.
