While watching live TV in openelec, hitting up or down arrow would show, for a few seconds, the channel number, channel logo, program title, program description etc... Hitting up or down arrow again while this information was up, would perform channel up/down.
In libreelec, hitting up or down arrow immediately performs channel up/down. How can the openelec channel info behavior be recreated? The keymap editor? Note that with very limited buttons on my remote that work with the rpi2's CEC functionality, the dual use of the arrow buttons was very convenient.
