I've searched for a similar issue, but couldn't find one. I hope it is not a duplicate. I also don't know if I found the correct component for this.

Please do not override standard browser shortcuts. I think overriding standard behaviors is generally a bad design choice - with exceptions, of course. People expect  software like Jira to add functionality not remove it.

For example, [CMD][F] / [CTRL][F] gets captured in the board and the backlog views. People - including me - use the browser's functionality. It is part of navigation.

Having to click in the menu bar and choose from a menu bar disrupts my workflow.
