Feature request: follow relative links in TUI mode

[MageJohn]

Often a directory of markdown files will have relative links to each other. It would be nice if in TUI mode it were possible to follow these links directly.

Note this is seperate from OSC8 hyperlink support (#237). That hands off following the link to the terminal, but in this case it would be useful if Glow were the one following the link so that it opens in the TUI.

To select the links, I imagine pressing tab/shift-tab to move between links and then pressing enter to follow the link. If mouse support is enabled, then it would be awesome to be able to use the mouse as well.

Would love to pick this up if it's available!

dart.md file is in the same folder as flutter.md, which contains a link to the former.

What you are saying is that that ./dart.md link should open the dart file? Hyperlinks are properly open when holding ctrl + left click, and opening the dart file should work the same way.

That doesn't seem to work in my remote setup with tmux. I think the idea is to navigate the links with some key and then following the link with enter. Something like command line web browsers do. It sounds to me like an awesome feature.

This would be really nice as it would allow to make a little interactive navigator for a network of markdown files.

I'd love this feature too so I can navigate between multiple linked markdown files without taking hands off keyboard!

Keyboard navigation of (local) links was the first thing I expected would Just Work (TM) beyond basic formatting and paging when I picked up Glow.

Keyboard navigation of links would be awesome. At the moment, I think this shouldn't be the task of glow, but rather of the $PAGER. The pager should allow for link selection and open the $BROWSER program with the link. The browser can then decide what to do with the link. For example, if it is a local markdown file (in contrast to a https url), it could execv a child glow process to open that file.

What do you think about this design?

Also note, that it might be possible to actually wrap existing pagers to provide such redirection functionality without changing the pager implementations. Some acrobatics with pty and OSC 8 parsing should do the job.
