XYplorer - QL-Win/QuickLook GitHub Wiki
XYplorer treats space as a part of search keywords, so QuickLook does not override it. However, it is possible to set a custom hotkey to invoke QuickLook.
To do that go in the User > Manage Commands...
menu. Select Open With
, then click New...
. Set the caption of your choice, then set the path to QuickLook.exe, surrounded by double quotes and followed by "<curitem>"
. You can assign a hotkey by clicking on the Assign Keyboard Shortcut
button:
