Connecting nodes without wires

Is it stated that double-clicking on a wire is supposed to highlight the other wires with the same name? I don't think this was ever supposed to happen(it does highlight the entire net it is physically connected to, but not the ones connected by name alone). In the lock_detect design, if you type Ctrl-F and search on pll_clk, it highlights both nets.

Note that double-clicking on a net is probably not the best way to find non-connected signals. The user would have to click on every net. Probably the best way for a generic search is to look at messages to see what logic gets removed(because of unconnected nets). The RTL viewer should work if you're looking for a specific net, but it sounds like you already know they're not connected since Ctrl-F can find one and not the other, i.e. they have different names. If you're certain they are the same, something strange is going on that needs to be debugged, rather than more tests on whether they're connected. (The schematic entry tool is probably not astoundingly better in the latest version of Quartus, but it's always a good idea to upgrade when you can.) Good luck.
