Editor Pane

The large pane in the middle of the Komodo workspace is the Editor Pane. The Editor Pane is used for editing and debugging. Each open file has a corresponding tab at the top of the Editor Pane. Change the order of the tabs by clicking and dragging tabs to the desired position. The name of the active file (that is, the file that is currently displayed in the Editor Pane) is displayed in bold text. Use the left and right arrow buttons on the right side of the tabs to scroll though open files. Use the close button “X” on the right side of the tab display to close the active file. An asterisk beside the filename indicates that the file has been changed since it was opened, and needs to be saved. If a file is under source code control, a file status icon to the left of the filename indicates its current status.
