In 7-zip pressing the backslash key takes you to the Hard Drive icons. In many keyboards the backslash key is next to or below the backspace key. This makes it very easy to accidentally press the backslash key when instead I wanted to press the backspace key.
Also, once backslash is pressed, there is no way to get back to the previous location. I usually close the window and reopen the archive when this happens.
It would be great if the backslash key shortcut was disabled by default. Optionally, a setting can be added to the options window to re-enable this for users who like this behavior.
