nit: Please document according to:
https://chromium.googlesource.com/chromium/src.git/+/HEAD/tools/metrics/actio...

Can you please add a note here that 'Accel_Rotate_Window' also included screen
rotation accelerator events prior to M58 (assuming it makes it into the M58
release).

[wutao, 2017/02/28 23:44:44]

Will add the note. It could be M59 depends when I get all the lgtm.

     Shortcut added to the homescreen with a valid Manifest. This action will be
