If it's the -view / reset all command : script:moi.view.resetAll();

Yup, PaQ has the right one there - that will work the same as the reset button, it will zoom extents to the selected objects the first time you activate it, and if you do it a second time it will zoom extents to everything.

Let me know if you want the shortcut for zooming extents for just one single viewport instead of all of them, that is slightly different.

PaQ Thanks for your kind reply, but I want a shortcut to run Zoom extens on a single view
Thanks in advance

Try this one then :

script:moi.ui.getActiveViewport().reset();

Thank you very much for your help.
Bye!
