The Node Locator provides an easy way to select nodes based upon (parts of) their name. When first clicked, the Node Locator will show a list of all nodes in the network (Figure 1). It is then possible to select any of these by clicking on them or by using the up/down keys to navigate the list, and enter to select a node.
It is possible to restrict the Node Locator to showing only nodes whose name matches an entered regular expression (Figure 2).
When specifying the expression, the following special characters can be used:
*: Match everything a number of times
.: Match everything one time
\w: Match a word character [a-zA-Z_0-9]
\W: Match a non-word character: [^\w]
\d: Match a digit: [0-9]
\D: Match a non-digit: [^0-9]
\s: Match a whitespace character: [ \t\n\x0B\f\r]
\S: Match a non-whitespace character: [^\s]
Note, in particular, that it is not possible to match a given character a number of times using the “*” character. I.e., the expression a*b will match abbbb as well as aaaab. Note further, that the expression is interpreted as having a trailing “*” character. That is, the written expression must only match the beginning of the node name for the node to be included in the list.
