Ok,
maybe then I still get your suggested workflow not right.

My need for this tool:
- I often have to use an accounting tool for different projects
- The projects often change
- The projects have cryptic names
- When I need to enter something for one of the projects, I want to open the list with the projects "ah ok, this time it's the project with the red t-shirt" select the "red t-shirt project" and in my accounting programm the cryptic name will be entered.

You could kind of also use mouser's FARR for that.
1. Create an alias with keyword value pairs in this format

[Select]

keyword | paste value
abc | paste 123
golf | paste don't forget to play golf

2. Set a regex pattern for the alias. For example

[Select]

^zz$

3. Set up a special hotkey in FARR to open FARR and trigger the alias (which then shows the list of keys). Under "Text for search edit box" add "zz" (the string that will trigger the alias).

But then you need to remember the keyword that will be replaced, am I right?
So you enter "abc" and it will be replaced by "paste 123"
