Hi Elaine, Thanks for a quick answer. The first two options do what I wanted. For the third option, assign the “centre’ function to mouse, I do not see this option in the right mouse menu. What am I missing? Best, Mirek On Jan 31, 2024, at 6:38 PM, Elaine Meng <meng@cgl.ucsf.edu> wrote: CAUTION: External to USask. Verify sender and use caution with links and attachments.
