BigStepForward during TimeShifting

CE 9.0.1 TX92 (S912) with TvH Server & Client.

When I pause (timeshift) Live TV I can skip forward and backwards through the timeshift period using the left and right arrows. That works a treat.

I want to use the up arrow to do a BigStepForward during the timeshift period. Presently pressing the up arrow changes up one channel whether in Timeshift or not.

So I used the Keymap Editor to remap the up key, but it’s function has not changed.

Here’s the generated Keymap Editor file:

				<key id="61568">bigstepforward</key>
				<key id="61650">audionextlanguage</key>

Any thoughts appreciated.
