Make searches in IRP events list (tags) assignable to shortcuts:

I have a bank with IRP events in it, that have tags.
Using the search box, I can currently type in a keyword, and the list of events will show only those, having a tag containing that keyword.
Perfect.

Now, instead of having to type into the events search box, I'd like to have a shortcut button (with e.g. a vMix script behind it), that:
* populates the search box with a keyword, as defined in the shortcut
* carries out the search using that keyword
* result: matching events are shown

Then, a second shortcut / script that clears the search, thereby showing ALL events again.

Thanks to anyone, considering to support this request.
