JEI version: jei-1.18.1-9.2.3.84
Forge version: 39.0.66
Minecraft version:1.18.1
Only one mod of JEI is available.
When I press 'f' in the JEI search box, it will exchange items with the deputy, I need to press again to enter.

I'm sorry my English is terrible.

This is so annoying. I experienced this bug too, but it simply does swap my selected item in inventory instead of typing in JEI, and reversely - when I try to swap item, it types in JEI.
Therefore now I try to type out everything by omitting "f", like "lywheel" instead of "flywheel" .-.

You can just change the hotkey, it's configurable in the Minecraft controls.
Something (maybe the modpack or a Forge bug?) changed it to a bad value but you can change it back easily without needing to work around the issue.

Thanks for the report!
There is a keybind to select the search box. By default it is CTRL-F.
It sounds like you are hitting this keybind.
Please check your Minecraft Controls and see that you do not have the keybind set to F.

I've encountered this issue with the f key and a similar issue with the o key (hiding the jei overlay). It seems that the default key bindings for both of these actions was at some point just the letter key without CTRL.

A few instances I've been using for a while had the letter-only keybinds, and I never changed them, but fresh instances have the correct key bindings.

Strangely, JEI has pretty much always used CTRL for these keys, there may be a bug in the way that the keys are saved by Minecraft or Forge or some other issue.
