^+o:: ;link text files in D:\Texts
WinGetTitle, Title, A
StringReplace, Title, Title, - Notepad, , All
thefilename := clipboard
FileAppend, %thefilename%, %thefilename%
Just select the entire file name, like "start.txt" or "start.rtf", and press ^+o.
You can, of course change the hotkey as well as the directory. It should also work with other file types, as long as they are registered in Windows. The script is not a wiki, of course, but its linking behavior comes close. If you use a rtf files, you have other markup as well. In fact, it is a very rudimentary wysiwyg wiki.
Postscript, Friday, November 16, 2018 at 20:29: I tried a slightly changed version of the script (different hotkey, different directory, changed StringReplace in line 4) with Jarte. It worked, but not reliably, that is, not always. Every once in a while it would not launch the file selected (even though it had done so before) In one sense that does not bother me, as I am more interested in connecting text files. What bothers me is that I cannot explain why Jarte and rtf files don't always work.
