Hey, thanks for the report and the screen recording. I can see what’s going on.
This is a known issue we’re tracking, and the fix has already shipped. Your version 3.18.9 came out before it, so updating Cursor to the latest version should stop the flyout menu from closing before you can click. Note: the third level of the menu (for example Linear > Issue > Created) is fully fixed only in the newest builds, so please make sure you’re on the latest version.
Until you update, here are two workarounds:
Type the trigger name into the Search Triggers… field at the top of the Add Trigger menu (for example “Linear issue”) and click the result directly.
Use keyboard navigation: arrow keys to move, right arrow to open a submenu, Enter to select.
