I use many years with Freewheel tool the cycle screen with the middle mouse button .
It very nice for me .
are other people to do that ?

A tip to import that to MorphOS ?

Now in MorphOS 3.10 is the middle mouse button for the inline editing by Ambient.
The choice for inline editing with left mouse long in gone by Ambient MorphOS 3.10.

Or i can't find it ....

I have a conflict for use middle mouse button for cycle screen and inline editing.
