Keyboard Shortcuts for quick editing?

Love the garmin virb edit app (thank you garmin).

However I am struggling to quickly "trim" videos. I am not that efficient with laptop inbuilt trackpad (mac osx). Takes me long enough to move the mouse to the video start point to trim, let alone move cursor again to choose trim left, split or trim right (yes am aware can right mouse click and chose menu option too).

Would be great to have frequently used editing shortcut keys for basic tasks like like trim left, split, trim right, or other common tasks, else at minimum keys to switch between modes (gallery, trim, g-metrix, transition etc).

Be great if can add this feature, else if is available if someone can point me in the right direction.
