Installation:
To install TypeMonkey as a dockable panel, place the TypeMonkey.jsxbin file in the After Effects/Scripts/ScriptUI Panels (MAC) or After Effects/Support Files/Scripts/ScriptUI Panels (WINDOWS) folder. NOTE: Don't copy the entire TypeMonkey folder into the ScriptUI Panels folder, just the .jsxbin file (otherwise After Effects won't be able to find TypeMonkey).
Next, drag the (TypeMonkey_TextMods) folder into the same parent folder as TypeMonkey.jsxbin (most likely the ScriptUI Panels folder). This folder is where you will install any third-party text modification scripts (such as language converters that reverse the word order).
