ViewDock is a UCSF Chimera extension for viewing output poses from several docking software packages. There is a tutorial on the Chimera web pages.

Keyboard shortcuts

Using ViewDock requires a fair amount of clicking and mouse movement. To reduce these you can use this Chimera accelerators script, mostly written by Tom Goddard (Chimera user list discussion):

Accelerators "cv" (Viable), "cd" (Delete), "cx" (Purge), work like clicking the radio buttons in the ViewDock dialog box - they change the status of the selected compound. Accelerators "cn" and "cp" move forward or back one compound. "ct" counts the compounds with each status, the output is shown in the Chimera "Reply Log" (Tools > Utilities > Reply Log).
