Apparently, Prism Launcher chose to adhere to the idiotic principle of the hidden "trashbin", .Trash-$(uid), invented by Ubuntu. Even though it's based on QT. This can't be disabled. It accumulated 139 GB of literal Trash, fully replaceable, over time. Just ... why? There's even an open issue about this, for over a year, referenced multiple times. I guess I have another point on my agenda.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hard delete used to be in the drop-down along with move to Trash, since I rarely accidentally delete things and when I do I have backups, I much preferred that arrangement.
Depending on your file manager, you may be able to hold Shift while triggering the delete to get a hard delete.
Shift+Del is pretty much standardized as the keyboard shortcut. And here on KDE, I can hold Shift while clicking the "Move to Trash" menu entry, too (well, it actually replaces the menu entry with one for permanent deletion, but that's effectively the same).
Shift-del
@troyunrau In mate it's a drop down menu not a key.
I don't use mate, but assuming that it has a file manager and that file manager has hotkeys that conform to the muscle memory that is built using other file managers... Try it and see what happens?
@troyunrau Ok did try, delete + center button mouse click does remove the file however since the only delete on my keyboard is right side and I'm right handed handed and and thus also use the mouse right hand, not terribly useful.
Well, that's on mate then. In KDE you could remap to a combo of your choice with ease
@troyunrau KDE wastes too much screen space and too much of my time. It's pretty but inefficient.
All I'm hearing is complaining. It's open source. Fix mate then so it does what you want.
@troyunrau Not complaining, just explaining my choice for a particular desktop and preferences. I realize it's open source and I realize I have the source so if it's severe enough I have the option of modifying it. If only I had infinite time.
