(There's no video for TheMouse2B 1.1 yet. Please contribute to MR and add a video now!)
TheMouse2B is a Control Panel which makes the second button on a multi-button mouse act like a control-click (i.e. in the Finder it brings up the contextual menu). TheMouse2B allows you to configure the second button to act like a single-click, double-click or even a click-lock.
It is mouse "brand independent" and ideally suited for using with the SheepShaver emulator which does not have "Right-Click" (or USB) mouse support built-in, as yet.
It is also now a Freeware - so the Shareware notices in the DL archive can be ignored.
Here is a quote from kelvin31415 on the E-Maculation forum:
(71.9 KiB / 73.62 KB)
System 7.0 - 7.6 - Mac OS 9 / compressed w/ Stuffit
68k encoded; Runs fine on PPC Macintosh.
Possibly can be used on earlier than Mac OS 8.0 OS's but is more suited for 8.0 - 9.2.2 for the "Ctrl Click" action to get a contextual menu.
Ideally suited to using with the SheepShaver Emulator (also Basilisk II), Mac OS 8.0 & later.
May have issues where an application, especially games software, takes away mouse control adding their own independent mouse controls for movement etc.
Emulating this? It could probably run under: SheepShaver
