Any chance for snippets?
The shortcut meter/measure formats in Notepad++ from whoever are awesome.
For an example you can look at
https://github.com/thatsIch/sublime-rai ... completion
You can even define your own snippets if you want by defining a new file for example you can take a look how Merlin did for this package
https://github.com/thatsIch/sublime-rai ... me-snippet
Important is the that defines that you are in a Rainmeter file,
is the command you want to define for that snippet to activate and content is obviously the content. for example are tab markers, thus would be the position after tabbing once.
