Finally commit a few improvements to the c200 (last version of FS#8824): In lists - long instead of short Rec to switch to the recording screen for consistency, one button 'resume' on long Right (disables the forced horizontal scrolling on long Left/Right though). WPS - put context menu on long Select for consistency, frees the short Down for entering the quickscreen. Virtual keyboard - enable line edit mode, additionally better navigating of the input line (Volume Up/Down to move left/right, backspace on Rec) and move accept to long Select -- see patch description for details (and everything I might forgot). Change the manual accordingly.
