Closing Windows
To close a file group tab or a file tab, click the X button of the corresponding tab or press Ctrl/Cmd-W.
To close a file tab without saving your changes, hold Ctrl/Cmd-Shift, and click the X button of the tab. This avoids having to confirm a warning message whenever you want to close an unsaved tab.
To close all files of a file group at once, right-click a file group tab and select Close All Files.
To close all file tabs but the selected file tab, right-click a file tab and select Close All But This.
To individually select the file tabs that you want to close, right-click a file group tab and select Select Files to Close. This opens the Files to Close dialog, where you can select the files that you want to close.
By default, files are removed from the project when you close them. To keep the files in the project even when you close them, right-click a file tab and activate Keep in Project after Closing.
