My fellow nerds: a question about your personal machines:

What is your favourite quality-of-life tweak you've made to your system?

An alias? A utility, a setting, something in .bashrc or ~/bin?

I'd like to know.

@mhoye I defined the right ALT key as the Compose Key.

@molenaar

I remap Caps as my Compose key

$ setxkbmap -option compose:caps

and use it DOZENS of times every day.

It's especially handy if you create your own ~/.XCompose file where you can include the system one

include "%L"

and then define your own atop it, so I have added some custom arrows, vertical ellipsis, the "Enter" key (⏎), and a number of emoji like

<Multi_key> <greater> <colon> <parenright> : "😈" U1F608 # SMILING FACE WITH HORNS

Also, it pays to skim through all the `<Multi_Key>` items in the system file to learn what's in there. Em- and En-dashes, horizontal ellipsis, diacritics, superscript/subscript numbers, and so much more.

@mhoye

As a side note, after messing with the ~/.XCompose file, you may need to restart applications for them to pick up the new key mappings.
