you have to press 2 buttons to enter "!" symbol, in the same time, for example, Google Chrome has search shortcuts without "!".
It is 'quick bangs' (Settings - Search - General) but it is limited to just '20 allowed maximum'
Moreover additional setting confusing users.
maybe Kagi can make bangs "!" symbol optional as well?
and remove 'quick bangs' setting?

so user will deside if he want to use "y Ocean" request to search "Ocean" in youtube instead of "!y Ocean"
