+    Metric recorded when the user rotate the screen using keyboard shortcut.

nit: rotate -> rotates
nit: using -> "using a"  or "using the"

Done.

+    "Accel_Rotate_Window" also included screen rotation accelerator

This sentence is unclear.  Did you mean to put (a clearer version of it) in the
Accel_Rotate_Window description?

[wutao, 2017/03/02 00:26:07]

No. The original rotating screen code used a wrong metric "Accel_Rotate_Window".
I am correcting it. So I created a new record "Accel_Rotate_Screen" and the
description is show that prior to M58, "Accel_Rotate_Window" metric included
some of user action of screen rotation.

How about I change it to:
This record was created in M58. All user actions under this category prior to
M58 were all included in "Accel_Rotate_Window"

+    events prior to M58.
