Opening files in Editor

To open the source of any file or element, select the corresponding node in the Commander or the Project View and press F4. Any files that you subsequently open will also appear in the Editor with their own separate tabs in the top of the window. The tab of the currently visible file is highlighted.
To flip between displayed files, simply click the tab of the file you want displayed or use the Alt+LEFT and Alt+RIGHT keyboard shortcuts.

To close a file, press Ctrl-F4 or select Close from the corresponding tab contextual menu.

Find a class by its short name

You may also quickly open a source file for a class by specifying its short name.
Press Ctrl-N (Search | Go to Class...) and enter the class name. As you type characters, the lookup window appears letting you choose the full class name. Select the required class and press Enter to open it in editor.
In case there are a few classes with the chosen name available, the list with all available classes shows up, letting you choose the one you need.
