[Chimera-users] Mouse control

[Elaine Meng]

Another thought is that maybe you didn’t know how to move the structure left/right/up/down (how to “translate” it).  By default, this is done with middle mouse button.  I don’t know if you have a middle mouse button.  If  you don’t, you can use the Chimera preferences (menu: Favorites… Preferences, then in the preferences dialog, see category “Mouse”) to change which mouse button does what.  You can just change it temporarily if you prefer.

The summary of how to move structures with the mouse (or touchpad, etc.) is here:

By “selected” I mean when you Ctrl-click on something in the main window, it is highlighted with green outline.  If you have something selected, you can use that same menu action to focus only on the selected part (the corresponding command would then be “focus sel”).
