Function: treemacs-toggle-node

treemacs-toggle-node is an interactive and byte-compiled function defined in treemacs-interface.el.

Signature

(treemacs-toggle-node &optional ARG)

Documentation

Expand or close the current node.

If a prefix ARG is provided the open/close process is done recursively. When opening directories that means that all sub-directories are opened as well. When opening files all their tag sections will be opened. Recursively closing any kind of node means that treemacs will forget about everything that was expanded below that node.

Since tags cannot be opened or closed a goto definition action will called on them instead.
