On Mint Cinnamon, alt+clicking apparently drags the current window. Meh; why, given tiling (whether manually with Super+Arrow, automatically with cortile, etc.)?
On Windows, alt+clicking directly on links lets you nullify the link-following so you can highlight the link text to then copy. This is a far more useful feature to me. Is there any way to change Cinnamon to do this?
Solution: Just disable the feature in the "Windows" settings' Behavior tab!
Aw yeah!
