Emacs on G+ is Useful!

Google+ is actually quite useful. Blogs is going the ways of dinosaur. In social networks, you can write, interact with people, immediately, post pictures, hangout (real-time text chat, voice chat, video chat). And it's all much easier than running a blog. If you follow web tech communities (e.g. TechCrunch, etc.), you know that death of blogs have been written on the wall for a few years. With few exceptions, such as professional blogger. (for a fun intro of g+, see: What is Google Plus and Google+ Songs (humor).)

Anyway, i wanted to say that running a emacs page on g+ have already been useful to me, even just after a few days. I learned emacs tips. Here's today's post.

Some slightly advanced emacs tips.

① I just learned about Keyboard Macro Ring today after 10+ years emacs using. (Thanks to Jorge A Alfaro Murillo.)

② A info doc node in emacs can be referenced by a elisp expression. For example: (info "(emacs) Keyboard Macro Ring"). Put cursor at end of paren then call “eval-last-sexp” 【Ctrl+x Ctrl+e】. That'll take you to the emacs doc. The argument to “info” is string of the node's name.

③ When browsing emacs info doc inside emacs, you can get the node's name by calling “Info-copy-current-node-name” 【c】.

keyboard macro is a time saver. If you don't know the basics, see: Emacs Keyboard Macro and Examples.

My emacs g+ and Twitter pages can be found at: Xah Lee Feeds. Please Subscribe! I will still write blogs. But it's more for heavy weight tutorials, and will be focused on elisp. (because, after a few years, all emacs tips all seem to be repetitions) Brief practical daily tips goes to @ErgoEmacs Twitter and ErgoEmacs g+. Thank you for reading.
