To remove an icon you press the red x in the icon list, and to remove all added icons you press the rubbish bin in that same list. To add an icon to a node, you either just click one of the icons in the leftmost icon-list or you press +c to get an icon palette that you can navigate with the arrow keys or select from with the mouse. To change the appearance of nodes you can add icons, change their style and their colour and you can format their text if you like. (If this annoys you as much as it annoys me, you change this setting in the preferences: under Behaviour you change selection method from delay to by click.) You can also select a key by placing the mouse cursor on top of it. To navigate between nodes use the arrow keys. To create a sibling node of the currently selected node, press. When a node is selected its background is grey, and you can rename it by pressing F2 or just start typing. To add a new node you press or and type its name. When you have typed a new name you press to confirm or to cancel. These are all common terms used to talk about tree-like structures in science.Ĭlicking the root node will let you rename it.
