MAC Laptop right click/drag mouse button TKinter

[spohle]

hi,

i programmed a small app with TK and use TK. some of the functions are
called with events like rightDrag and rightClick on an item on the
canvas. that works fine on a pc. on my mac laptop i only have the one
button, so im used to use CTRL+ Mouse Button. that doesn't work with
TK.

any ideas how to get around that problems ?
