Unable to bind TAB to insert selected word

[domonnss]

problem

I want to use TAB to complete my word instead of ENTER.
But failed

I can't just bind TAB to it without modifier
Then I tried to write the code in .obsidian/hotkeys.json

But it didn't work too.Because of the modifiers ,I guess.

suggestion

In another plugin "various complements",I can bind TAB to any hotkeys in a easy way.
Could you please implement the function?

Or provide any method to anchieve my goal?
thank you <3
