move a node horizontal or vertical

Question

Hello, is it possible to move a node horizontal or vertical? Best would be by arrow key or by mouse plus an other key.

Answer 1

Yes, you have to select the node and move it with the mouse alone.  If you hold the alt key whilst dragging, you can override the snap-to-grid setting if it is on.

Answer 2

There is currently no way to restrict movement to either the x-axis or the y-axis only. However, with snap lines enabled ("View" -> "Snap Lines", should be enabled by default), yEd will snap to the original x- or y-position when you move the node close enough to said original position. How close "close" is, is determine by the settings in "File" -> "Preferences", tab "Snap Lines".

Alternatively, enter desired coordinates for selected nodes directly in the properties table in yEd's lower right corner.
