how to add left-click context menu to mate-desktop
I am using the Redmond theme on Ubuntu mate-desktop running as a Windows 10 guest on VMWare. I would like to add my own left-click and middle-click actions to the desktop. I've seen suggestions related to caja, gnome, etc., and am just wondering which layer to leverage. Ideally, mate-desktop will have a gui-based way to create custom actions. I do not think this is the case given what I see in mate-tweak and preferences->menu. Other suggestions were to do it at the caja/nautilis or gnome level. I could probably also do it with a mouse app like FastKeys or InputRemapper, but prefer something more "natural" if that makes sense.Does anyone have any suggestions as to the most Mate-like way to do this? (By Mate-like, I mean directly in Mate or in one of the frameworks from which it forked.)
My current research is on caja, which, so far, seems analogous to explorer in Windows 10. For example, I recently ran into an issue in VMWare where the desktop background was not resizing when I resized the VMWare guest window for the vm. (The panels would resize, but I could not right-click (for example) and pull up the context menu on the area of added size. Also, the background image tiled over the new area) Interestingly, if I resized even a very small amount SMALLER, it would refresh and fix it. Also, if I logged out and back in, it would fix it. Eventually, I determined that:
killall caja
Would also refresh the resolution of the display. As such, I theorized that caja was running the desktop as well as the file manager. From there I started also looking into nautilus since caja was forked from nautilus; however, i still have not discovered how to add a left-click menu. Any suggestions on how to go about this would be great. Thanks!
