Mouse bindings

You really must have a three button mouse!!

By default clicking with the left mouse is used to identify an object, the middle mouse button is used to paste and the right mouse button is used to bring up a pop-up menu. To rotate the display hold down the left mouse button and move the cursor left-right or up-down; to translate hold down the middle mouse button and move the cursor in the direction that you want to drag the display. To rotate about the z-axis (i.e. the axis perpendicular to the screen) or translate in the z direction hold down the shift key and use the appropriate mouse button. Note that dragging downwards brings things forwards.

To rotate or translate a selected object use the same mouse buttons and movements but also hold down the x key. To select the moving object use the Move command on the objects icon menu. The moving object is indicated on the Display Table by .

The bindings can be changed from the Mouse bindings interface that is in the Behaviour folder of the Preferences window (accessed from the Tools menu).



This interface lists the actions and the mouse and key bindings for the action. The binding can be to left,right or middle mouse button, the Shift and/or the Ctrl keys can be depressed and any one other keyboard key might be depressed (this set in the right hand column of the interface). The interface also has the option to set the bindings to the default bindings of different molecular graphics programs. Note that other programs may have feature which is not supported in CCP4mg and we have needed to make slight changes. The convention in CCP4mg is that the transforming individual objects uses the same bindings as the equivalent view transformation but with the x key depressed. Maintaining this convention while using Coot bindings is difficult; the f key is used.
