I have defined Command-Option-h as \href{•}{#SEL##INS#}• in the Macro-Editor and I can test it without any problem (using the Test-Option inside the editor). But after restarting TeXShop it is not working. Other definitions like Command-Option-e for \enquote{#SEL##INS#} are working properly.
Are there combinations which are forbidden to use?
