The cursor icon will also change depending on the selection mode.

- multiple objects overlap
- multiple objects very close to each other
Action: it will show a pop-up window of nearby objects and to cycle through them. To make this type of selection the default, and thus not require the use of the Alt
key, change the advanced preference selectaction.cycles.multiple.matches
to true. Holding Ctrl
afterwards to directly select an object.
Double mouse click to select object around cursor
Cursor: none

- - any ways which are entirely within the rectangle will be selected
- - previously selected objects will be replaced with new object(s) and displayed in Selection List Dialog
- Hold the
Right mouse button
when releasing the left mouse button - cancel the selection rectangle

Move
You can move selected nodes and ways in the main window, by moving the mouse cursor close to one of the selected objects and then left clicking while dragging the mouse.
- If the mouse cursor is near a node when performing the move action, then just this node is moved.
- If you move a node very close to another node and hold
Ctrl
when releasing the left mouse button the moved node will be merged with the other node.
- If you move a node very close to another node and hold
- If the mouse cursor is near a way when performing the move action, then this way, together with its associated nodes, is moved.
Moving objects is also possible with shift + arrow keys
.
Merge nodes

Scale
Cursor:
Activation steps: Ctrl+Alt
+ Left mouse button
and moving mouse up and down
Action:
- scale selected nodes and ways around their geometrical centre. Proportions will be kept.
- if used only on 2 nodes, it will move them from their mid point
Advanced details
Whether a mouse action is considered a selection or a move depends on some settings, to prevent objects from being moved when a simple selection was intended; this is particularly important on devices such as tablets that are touch sensitive or use a stylus. If the pointer is moved between pressing and releasing the left mouse button, the object will only be moved if the pointer moved more than 5 pixels or was held down for more than 0.2 seconds, otherwise the object will simply be selected. These two settings can be changed with the advanced preferences edit.initial-move-threshold
(pixels) and edit.initial-move-delay
(milliseconds).
