Ctrl-Click	Holding the "Ctrl" key toggles element selection.

Shift-Click	Holding the "Shift" key and clicking on a way segment only deletes this way segment and not the whole way.
Ctrl-Click	Holding the "Ctrl" key deletes object and references (i.e. ways using this node).
Alt-Click	Holding the "Alt" key and clicking on a way only deletes the way without its nodes.

Ctrl-Click

Holding the "Ctrl" moves way segments along their perpendicular (orthogonal to the arrow direction of the way segement).

all modes

Click-RightMouse	Click and drag to move the map.
Scroll-Wheel	Zoom in and out.

Note: In ​gnome desktop environment "Alt"-Click is used for moving the window. The "AltGr" key can be used instead; note that on some keyboards the "AltGr" key is simply the right-hand "Alt" key.
