Lintalist
Lintalist allows you to store and (incrementally) search and edit texts in bundles and paste a selected text in your active program. The text can be interactive, for example you can automatically insert the current time and date, ask for (basic) user input or make a selection from a list etc and finally it can also run a script. You can use keyboard shortcuts or abbreviations to paste the text (or run the script) without opening the search window. You can extend Lintalist by writing your own plugins. Lintalist is open source and developed in AutoHotkey.
