If the BEAMER_col property is also set, something like C[t] can be added here as well to set an options argument for the implied columns environment. c[t] or c<2-> will set an options for the implied column environment. ~~~ This does work in the example presentation at [1], but it seems only for B_block entries. I was trying to use B_beamercolorbox, where presumably the color selections (fg=, bg=) should be environment arguments, but this is ignored. What's more, if I take the colors out of the color box's envargs and replace it with another argument syntax -- <2-> -- that definitely works with B_block, this is also ignored. So it seems, if you wanted to have a colorbox appear in a later overlay, you would be screwed (would have to write the LaTeX by hand). A bit confused. Or, the simple question -- how do you set the colors of a color box in Beamer export? Oh, wait, I just figured it out... though you would have to admit, this is not remotely obvious. ** Frame 2 \\ where we will not use columns #+LaTeX: \setbeamercolor{ybg}{bg=yellow} *** ybg :B_beamercolorbox: Please test this stuff! :PROPERTIES: :BEAMER_env: beamercolorbox :END: It kind of strikes me like an epic hack: you have to name the headline after the Beamer color ID, instead of naming the headline after the content... not very /org/anized. Worth a bug report or feature request? hjh [1] http://orgmode.org/manual/Beamer-class-export.html -- James Harkins /// dewdrop world jamshark70@dewdrop-world.net http://www.dewdrop-world.net "Come said the Muse, Sing me a song no poet has yet chanted, Sing me the universal." -- Whitman blog: http://www.dewdrop-world.net/words audio clips: http://www.dewdrop-world.net/audio more audio: http://soundcloud.com/dewdrop_world/tracks
