Each of these actions apply to a specified set of nets. net and pin are patterns which match one or more nets or pins; these patterns may be full names or regular expressions. If an exact match is found, it is the only match; if no exact match is found, then the pattern is tried as a regular expression.

If neither net nor pin are specified, all nets apply. If net is specified but not pin, all nets matching net apply. If both are specified, nets which match net and contain a pin matching pin apply.

freeze, thaw and forcethaw temporarily prevents changes to the netlist from being reflected in the GUI. For example, if you need to make multiple changes, you freeze the netlist, make the changes, then thaw it. Note that freeze/thaw requests may nest, with the netlist being fully thawed only when all pending freezes are thawed. You can bypass the nesting by using forcethaw, which resets the freeze count and immediately updates the GUI.
