Hey there, you do have the flexibility to customize key bindings in Retool on a per-app basis. To do this, open the app settings menu by clicking the gear icon in the left panel. Select 'Custom shortcuts' and click '+ Add new' to create a new shortcut. Specify the desired shortcut keys and the JavaScript action to trigger. You have a wide range of keyboard characters and optional modifier keys at your disposal for customization.
Thanks for explaining the issue. Have you considered using a different web browser like Chrome? Switching to Chrome could be a practical solution to avoid the keybinding conflict altogether.
Since it appears that customizing keybindings in the IDE isn't currently supported as you've mentioned, an alternative approach could be to modify the keybindings within your Firefox browser itself. You can refer to this documentation for instructions on how to customize keyboard shortcuts in Firefox: Customize Keyboard Shortcuts in Firefox.
In the meantime, I've gone ahead and filed a feature request for this issue. Thanks for bringing it to our attention.
Thank you for your feedback and patience. We value your continued use of our product and will keep you updated on any progress related to this feature request.
Chrome on Windows and Linux share the CTRL+U shortcut conflict. So, like Firefox on Mac, the shortcut to open inspector is not useful on these platforms either.
