Here is an update to the softkey mods for V2.6 of Tytung's Jellybean ROM. There are two modifications, landscape softkeys and a soft power button.
The installer ZIP file can be downloaded from this link: https://dl.dropboxusercontent.com/u/22856583/NexusHD2-JB_V2.6-SoftkeyMods.zip
. The file is flashable from recovery. There are individual options to select the landscape softkey mod and the power button mod in any combination.
I suggest that you first install or update your phone to V2.6 of Tytung's ROM and boot it up before you install these mods. A few minutes after boot-up, go back to recovery and install these mods.
Installing the power button mod adds two options to the CyanogenMod navigation bar editor, an invisible power button and a visible power button. After installation, you have to turn on the mod by going to Settings->System->Navigation Bar Buttons and layouts. Click the lock icon, then the small plus sign at the left of the navigation bar. Scroll to the power button option you want (either invisible or visible) and click it. Finally, click the lock icon again.
If you previously had the power button mod installed and you do an update, you don't have to turn-on the power button mod per the previous paragraph. The settings will be preserved through the update.
Note that Tytung reduced the navigation bar height in this version of the ROM, so the previous LockFix mod is no longer needed. And the reduction in height addressed Elveneleven's request.
EDIT - the download file has been updated to fix the issue with the navigation bar height.
