[Arjen Markus] (1 march 2018) Yesterday I saw an announcement of a tool called HyperKWIC. It is meant to allow you to navigate your source code, though it is advertised as a documentation tool - as it is neutral wrt the programming language (you can declare a small set of properties for the programming language you're using) it may not be the smartest tool, but it does look useful. I merely extended the language configuration file a bit and it already was able to handle Tcl code. See the screenshot below. If you are interested, you can find it here: www.hyperkwic.com. It is also freely available for non-commercial use. <>Category Tools
