right click for menu with choices (to change font size)?

Question

I am using emacs 26.1 under macos. when I right-click with the mouse, emacs seems to want to select the region. alas, I would prefer to see a popup menu where I can select a few choices that I would like to choose---save file, close buffer, increase font size, decrease font size, change fore/background theme. is this possible?

Library mouse3.el gives you what you request: a context-dependent right-click popup menu that's configurable.

See Mouse3 for a complete description, screenshots, and details. By default such menus are region-related if the region is active, and it is global and click-position-related if not.
