Web player intercepts ⌘⇧M and blocks Chrome profile-menu shortcut #2596

Description

Cap's web video player intercepts ⌘⇧M (Command+Shift+M) on macOS, preventing Chrome's open profile menu shortcut from working when the player has focus. The player treats the modified shortcut as its plain M mute/unmute command and cancels the browser's default action.

Reproduction

1. Open a Cap share page in Google Chrome on macOS, for example https://cap.so/s/mdvxms2gfmkgc0e.
2. Focus the video player or one of its controls.
3. Press ⌘⇧M.

Actual: Cap consumes the shortcut and toggles mute instead of allowing Chrome's profile menu to open.

Expected: Browser shortcuts containing Command should pass through. Plain M should continue to toggle mute.

Additional Context

• Affected component: Cap web share-page player (not the desktop recording app).
• Browser / OS: Google Chrome on macOS; the original reporter's exact versions were not collected.
• Live-page diagnostic: With the player focused, dispatching a cancelable keydown with key: "M", metaKey: true, and shiftKey: true changed the video's muted state from false to true and set defaultPrevented: true. This verifies the page handler consumes the modified key event; the diagnostic used a synthetic event, not a native Chrome profile-menu interaction.
• Likely cause: the player's keyboard handler switches on event.key.toLowerCase() and calls preventDefault() for m without checking Command/Control/Option modifiers. Source:

• Suggested fix: ignore Command/Control/Alt-modified events before processing plain player shortcuts, while retaining intentional Shift-based shortcuts such as playback-speed controls. Please also check other letter shortcuts for the same browser-shortcut collision.
