The Preferences dialog can be opened fron the menu (File >> Preferences...).
It has the following tabs:
General, Display, Editor,
Background, Modules,
Snap Lines, Grid.
If set, the Welcome screen will be presented on each yEd startup.
If set, yEd checks whether a newer version is available at the yWorks web site on each startup.
If set, the first label of each edge and node will be displayed as a tooltip when hovering with the mouse over these objects.
Allows choosing the default language of the editor. Currently, the languages German and English are supported. Changing the language comes into effect after the application has been restarted.
Controls how many levels of undoability should be provided by the editor. The higher the value, the more memory will be used.
If set, zooming will be animated, i.e., zoom factors and viewport position will be interpolated.
Determines the maximum number of different graph element samples that are shown in the section "Current Elements" of the palette tool window.
If set, the control points for the edges in the palette will be drawn.
If set, antialiasing techniques will be used when rendering graph objects. Setting this option increases the rendering quality, but also slows down the rendering process.
This value specifies the length that is clipped (not drawn) from both ends of an edge path.
If set, edges will be rendered before nodes, i.e., the nodes will always be seen at the front.
This value specifies the zoom level beyond which graph elements will be painted sloppily. The smaller the value the farther you have to zoom out in order to see a sloppier painting.
Determines how to render edge crossings.
Determines whether to scale bridges that span multiple edges.
Determines which order of a set of crossing edges should be used to determine where to insert bridges. Crossing determination mode affects, e.g., whether all bridges are oriented into a single direction or not.
Determines the strategy for updating the context views: either when a graph element is selected or when the mouse hovers a certain amount of time over a graph element.
If set, a single mouse click (with the left button) on any empty location in the
editor creates a new node (unless there is a current selection).
If not set, new nodes can still be created using the clipboard (Copy and Paste)
or by dragging a node sample from the palette into the active editor window (using a
mouse drag gesture).
If set, changing the label of a group in its open state changes the label for the closed state of the group, too, and vice versa. Moreover, new groups are created with matching labels for their open and closed state. If not set, the label for the open and the closed state may be different and can be changed independently.
If set, the target end point of an edge always snaps to the center of the target node. If not set and Orthogonal Edges are active yEd tries to make a suitable decision for placing the end point.
If set, nodes and edges created by drag and drop from the palette get selected.
If set, a consecutive numbering is used for the label of newly created nodes. Otherwise, the label of newly created nodes remains empty.
If set, upon node creation the label of newly created nodes can directly be edited.
If set, upon edge creation the label of newly created edges can directly be edited.
Determines whether the node size gets automatically adjusted to the label. If set, the node size is adjusted whenever the label changes. Internally the Fit Node to Label tool is used. Thus it is possible to fine tune the node size adjustment by changing the settings of the tool.
If set, all bends from the start or end point of an edge to the last bend before the path of the edge is leaving the node get deleted. The last bend gets the new start point of the edge.
Determines whether in Edit Mode the scrollbars to the right and below the canvas are shown. If the scrollbars are not shown, then the current viewport (the visible diagram area) of the editor window can still be changed by dragging the mouse with the right button pressed.
You can choose whether the ENTER key closes the label editor or creates a new line.
Determines the mode, which should be used to render the background of the graphs.
Determines the color to be used as a background color.
Specifies the image to be used with the above modes.
If set, the calculated layouts will be applied in an animated fashion to the original diagram.
Allows to influence the way how a layout is morphed.
Determines whether options should be displayed prior to the invocation of the layout algorithm.
The details are described on a separate help page.
Specifies the color of the snap lines.
Specifies the snap distance between nodes.
Specifies the snap distance between nodes and edges.
Specifies the snap distance between edges.
if set the end of an edge snaps at multiples of the edge to edge distance with respect to the center of the node if it is moved along the border of that node
Specifies the color of the grid marks.
Specifies the distance between two grid points.
Specifies the visual appearance of the grid.
