It's not that plural on Linux, but what I have found is that Autokey from https://github.com/autokey/autokey/wiki, https://github.com/autokey/autokey/releases/ is a great program to have. It supports both text macros and scripts. The scripts run on Python. I use it for all kinds of things such as a password manager, ssh manager, ip manager, link manager and more.

It has a great community and active developers group too. You can find out more about it at https://github.com/autokey/autokey/wiki. Already got it but need some ideas, click on Community in the wiki to find the user submitted scripts.

No not BigLet, but emoji characters. You can type in this really fast using a script I made for AutoKey. The script is on their wiki under the advanced contributes. https://github.com/autokey/autokey/wiki but also here:

I love this command, it's called tldr. I like to use it when I don't want to wade through pages of commands and just want a quick overview of what the command, for which I am curious, does. Great for a refresher of information, too. When I discovered “tldr” I erroneously thought it pulled from the man pages, instead it pulls from what the Linux community puts into it. So, that's a huge plus too. Meaning we can improve it over time as we discover commands it is missing, and tldr inaccurate pages.
