Emacs Elements has a new video that takes a quick look at Bookmark+. It serves the same purpose as the builtin bookmark application but is extended in many ways. I’ve been using it for many years ever since abo abo wrote about it and his hack to make jumping to bookmarks easy (I wrote about it here).
The video details some of the additional types of bookmarks that bookmark+ supports. You can, for example, set a bookmark to a URL and bookmark+ will open it in the browser for you. I use that all the time to quickly jump to the Irreal site when I’m working on a post.
Another nice capability is to open a specialized buffer. For example, I have a bookmark to Ibuffer that will open a buffer with the current buffer list. Similarly, you can set a bookmark to a directory. That can be convenient when you have a directory with a long path. For instance, I have a bookmark to the the elpa directory that lives in the (for me) hard to type .emacs.d directory. When you open such a bookmark you get a Dired buffer for the target directory.
The video demonstrates another bookmark type that I don’t use but could be handy: you can mark a region in a file and bookmark that. When you open the bookmark, you jump right to it and it’s highlighted. Similarly, you can bookmark any position in a file although this may be possible with native bookmarks too.
The video is definitely worth a look. It’s 8 minutes, 13 seconds so it should be reasonably easy to find time for it.
