MODO keeps a listing of every command used during a session in the Command History viewport. This view is useful for quick undo/redo operations, managing macros, quickly assigning keyboard shortcuts to specific commands and many other utility functions. To access the Command History, look at the bottom right-hand corner of the interface where there is a single 'Command' input field, then drag the divider upwards that is just above that panel until the Command History Header is displayed. Once opened it should look similar to this-
There are five tabs in the Command History panel: 'Undos', 'History', 'Commands', 'Scripts' and 'Results'. By default the 'Undos' list is active. Within this list are sections for 'Command', 'Fired Name and Arguments' and 'Description'. The listings within these columns display the internal commands that are fired when any keyboard shortcut or interface element is interacted with. Users can LMB+click and drag within the Command list to undo/redo. Simply locate the line that reads "Drag to undo/redo" set in bold and then simply drag it up to undo multiple commands at once. To control the maximum number of available undos, go to the System menu and choose "Preferences > Defaults > Application" then adjust the value in the 'Max Undo Level' numerically in the input filed or adjusting using the available mini-slider.
Keyboard shortcuts can also be simply assigned in this view by RMB+clicking any command item within the list and selecting the 'Map Command to Key' option opening the key assignment popup dialog.
In this dialog users can see the command the shortcut is being assigned to in the 'Command' section (which should be a duplicate of the command that was clicked on). Then the user is prompted to press a keyboard key, or multiple keys in combination, which will appear in the top area (it will be noted if the intended combination is already in use by another command). If desired users can also use the "[Anywhere]" menu to define a specific location of the interface where the keyboard shortcut should be dependent upon (i.e. limited to a specific active viewport when the keyboard shortcut is applied). Once a key combination is assigned, pressing 'OK' will actually assign the key and save the shortcut to the configuration file.
Clicking on the subsequent section of the viewport opens the 'History' tab, where a history of the fired commands are listed with their possible attributes. The 'Commands' tab supplies a complete list of all the commands available within MODO. The 'Scripts' tab will give users access to all recorded macros stored in the config. From here it is possible Edit or Run individual lines within these scripts. In the 'Results' tab, any results of command firings or queries is displayed here.
