i searching in userpreference <theme.
but,i can not found timeline tab.
can i change time line color?(not dope sheet)

and other question.
When i deselect it in Editmode, i have to press A key twice. Is there a way to do it at once?
i can not found this setting in userpreference<input

For the grid lines, see under Dope Sheet > Grid

For the background, Dope Sheet > Theme Space > Window Background

I’m not sure on your second question. A toggles select all. If you have a vertex selected, one A press will deselect the vertex. Another A press will select all.

Unless they were changed again, I believe the selection controls in Blender 2.8 are:
A: select
Alt + A / double tap A: deselect
