They might be searchable on the wider internet if you’re looking for info on them, but I can never remember them when I need them on the actual system.
On my windows PC, I type ‘note’ and slam enter to open notepad a thousand times a day without a problem. On my KDE desktop ‘text’ seems to 50/50 bring up… whatever the text editor is called and 50/50 something else. Apparently “Kate” is what I’m after.
There is real value in naming things after what they do and it’s my sole gripe with KDE that they have stupid names.
