Sublime Text 3 macro for inserting \onslide<> and placing the curser between the angle brackets. Used when writing Beamer files. For ST3 to see this macro, it needs to be installed in the ST3 Packages/User folder. On my systems this folder is stored in Dropbox so it can be symlinked to the folder on the local mac.
