The problem#
While I use the command-line and keyboard-based interfaces a lot to manage files, I also regularly use graphical and mouse-based interfaces. As with any time there's different ways of interacting with a system, there's some times when in one mode when you want the features of the other.
The solution#
Xfce's file manager Thunar has a feature called custom actions, which lets you add menu items that run commands on files or directories you are viewing or selecting.
The documentation suggests multiple ideas of actions you might want, including converting among different formants, rotating images, and various file management actions like viewing disk usage and bulk moving files. Additionally, the default action "Open Terminal Here" is one I use frequently.
