Hi again, While writing my previous email, I just thought of another thing. As it is unrelated to the other one, I'm creating a second email... The only thing I miss in org lies in org-beamer: it is the ability to use the star '*' in BEARMER_ACT, with something like: * my block1 :PROPERTIES: :BEAMER_ACT: *<1> :BEAMER_ENV: block :END: + my content1 * my block2 :PROPERTIES: :BEAMER_ACT: *<2> :BEAMER_ENV: block :END: + my content2 which would make the 2nd block appear "in place" of the 1rst one. I end up doing things like: #+LATEX: \onlide*<1>{ * my block1 * @@l:@@ :PROPERTIES: :BEAMER_ENV: ignoreheading :END: + my content1 #+LATEX: } #+LATEX: \onlide*<2>{ * my block2 * @@l:@@ :PROPERTIES: :BEAMER_ENV: ignoreheading :END: + my content2 #+LATEX: } Its works but it makes my org files look very ugly :{ I know block do not natively accept *<1> notation, but it would be great if org would detect the * in BEAMER_ACT directive and translate that into some code similar to the one I generate manually (#+LATEX + onslide* + shadow "ignoreheading "closing block). Any thoughts on this? -- Guillaume MULLER
