tl;dr FR: Settings entry so that I can choose which character invokes the smart-picker.

For developers, the forward-slash is annoying as I want to enter unix paths into Spreed or other places all the time.

Is your feature request related to a problem? Please describe.

I run a nextcloud instance for a company of software developers. It can be very annoying having the Smart Picker command invoked by the forward-slash / character. Very frequently I am middle click-pasting a path to a folder on a server to a colleague for them to find some data etc. into Spreed/talk, only to get back the winky bot face that the command doesn't exist. Now I understand what used to be bot commands are better integrated into the smart-picker (hence I've not opened this against Spreed), and whilst I'm yet to look into it further and learn how it works and how we could do all sorts of cool things with it, since updating our server this is now starting to happen in e.g. markdown files, and I presume will only grow over time.

All a great idea, like the concept o expanding functionality thoroughly. But, if I could have an admin setting to change the character used to trigger the picker, that'd be really helpful, as I want to type something starting with a forward slash in a hurry on average once a day. I may be on a call with colleagues debugging something for example, and Spreed is easier for me than any meeting chat, so whilst multitasking across many windows, I often paste commands in verbatim for people to run whilst they're sharing their screen.

I understand most enterprise users are probably not entering likely to be entering paths, and if they are, not paths separated with unix slashes but instead Windows paths. However, for I presume a small minority, it is rather annoying having to escape everything with backticks or trying to fool the system in some way. So I figure if it hits anyone as much as it does for me and my colleagues, there may be others out there who for entirely unrelated reasons would like to change the character for the smart-picker to something else too; so am suggesting addition of it as a setting.

Describe the solution you'd like

Something in the Admin Settings page where I can enter (presumably a single character, maybe a string is more flexible - but I don't know how sensible this would be) that determines the character for triggering the picker. I've looked through the pages in our installation and don't see an obvious page, so will let others chime in on where would be the most sensible. A keyboard shortcut also might have some advantages but might be hell to implement from within a browser.

Additional context

I have searched for open issues. I would not be surprised if this has already been reported, but github's search tool seems to get worse and worse at filtering in only relevant search results, so despite using as many permutations of keywords as I can think of, I haven't found an existing issue - nevertheless, this may be a duplicate, or something discussed on the forums ;)
