1. I'm a happy (64-year old, retired) enduser of textmate, not a programmer. 2. I'm using a textmate project as my "personal textbase". The project has many markdown files. I don't use markdown as a source to convert to html but as the real thing, as my final product (with an occasional preview for reading convenience). 3. My markdown file is a container for one or more articles, each about a separate topic. Every article is uniquely identified by a tag in the form of a string "tagid=<tagid>". 4. I'm using crossreferences to other articles in the form of a string "tagref=<tagid>". 5. To link from a tagref to the associated unique tagid I use the "Find in Project" dialog. I type "tagid=<tagid>" and click the single link in the result to load the relevant file. 6. I love to have the following command: with the caret in a "tagref=<tagid>" reference and pushing the enter key, the relevant file automatically loads. 7. I have no idea how to make this command; help is appreciated.
