Not sure if this belongs here, but it is reported for Linux Mint 17.3 which uses Plasma4 and Linux Mint 18 which uses Plasma 5, right?

After using it and analysing a little more, I don't think this is a good feature. It's main problem is inconsistency. There is no intuitive way to know when the right button of the mouse will replicate the left button or if it will act differently.

For example, right-click opens the context menu and then there are several ways of choosing one of the options in the context menu. As an example, select this text and then press right button. From here there are three ways of copying the text to clipboard using the mouse:
1) release right button before moving the pointer, then choose "copy" by pressing again the right button (ie right button is equivalent to left button)
2) "normal" way: release right button before moving the pointer, then choose "copy" by pressing the left button
3) keep pressing right button and release it over the "copy" option (ie right button is equivalent to left button)

In cases 1 and 2 we can say both buttons are equivalent (they can choose one option in the context menu).
But then in several other cases buttons are not equivalent (for example I can not press "OK" using right button in a file save dialog)

Therefore sometimes buttons are equivalent, sometimes they are not. Maybe the only place cases when they are equivalent is when choosing options from a context-menu?

IMHO, choosing should be always by left click, to avoid threads like this one... And, ideally, this behaviour could be configured in system settings if anyone wants otherwise... just my opinion.
