There's a shortcut - just select one edge, then do Ctrl+A (or on the side pane click on Select / Sel all).

When you have an edge selected, then you can do a "select all" to select all the other edges on that one object.

Invert works in the same way, if an edge is selected then it will target edges.

Also if you select a single edge, it will also set window selection (where you click in an empty area and drag to make a selection box) to target edges as well.
