TransformModeCycler is a set of four macros for 3ds Max created by Martin Breidt. Each macro is intended to be assigned to a keyboard shortcut, with the combination Q, W, E and R offered as an example. Once assigned, the macros switch to different select and transform modes and cycle through the most commonly used coordinate systems.
The release is version 0.1 and is listed with compatibility for 3ds Max 4. The set has been marked obsolete since R5. That note, together with the listed compatibility, ties the macros to older releases of 3ds Max rather than current ones.
The script is listed on ScriptSpot, and Martin Breidt's site at breidt.net hosts this script alongside his other 3ds Max tools. Check the developer's page for the current files and any details on later releases.
