I have several keyboard entry languages set up, and can easily select the one I want to use from the indicator menu. Once a language is chosen, the menu item "Keyboard Layout Chart" shows me what key generates what. How do I print the keyboard layout chart in Ubuntu 14.04? There is no Print button on the chart and there is no menu associated with the layout chart window. Perhaps this is a but in 14.04?
The basic idea should be to use
xkbprint :0 -o one.ps ps2pdf one.ps evince one.pdf
The step through
ps2pdf is needed here because otherwise the generated postscript is troublesome to view.
In principle it should be possible to add all the AltGr combinations to the map, but I never found the exact incantation to obtain it --- I mean, the neat map with 4 symbols per key.
