Command History

The Command History window is invoked by clicking the Command History... button on the right side of the Command Line. It lists the commands that have been entered in the Command Line since Chimera startup; individual commands or blocks of commands may be chosen (highlighted) using the left mouse button. The choice of a single command, but not a block of commands, can also be moved up and down the list using the keyboard up arrow and down arrow or Ctrl-p and Ctrl-n. Ctrl-click adds to an existing choice rather than replacing it. To highlight a block of commands without having to hold down the mouse button, click on the first (or last) command and then Shift-click on the last (or first) command in the desired block.

Clicking the Execute button causes execution of the highlighted commands; double-clicking an individual command executes that particular command. Clicking Record... brings up a dialog box that allows the highlighted commands to be saved to a new file or appended to an existing file. Either the commands or their Python translations may be saved. Clicking Help brings up a browser window containing this manual page, and Close closes the Command History window.

The commands in a file saved with Record... can be executed with the source command, or executed automatically when the Command Line is shown (see the Midas preferences).
