CTRL+SPACEBAR allows you to alternatively select and deselect a file in MS-DOS version 5.0 Shell.

This keystroke is particularly useful when the Select Across Directories option is selected from the Options menu. By pressing CTRL+SPACEBAR, you can deselect a file after switching to a directory in the directory tree.


When selecting a new directory from the directory tree, if you decide to scan through the list of files with the keyboard, a file is selected. This is due to the normal operation of MS-DOS Shell. If Select Across Directories is activated and you perform a file operation, all files that have been marked during any such perusal will be acted upon.

To avoid this problem, after scanning through a list of files, be sure to press CTRL+SPACEBAR to deselect any files you do not want to act upon.
