One of the useful features of an editor is the ability repeat commands with minimal keystrokes. Many users find it useful when having to execute arduous long commands that require some typing.

One of the features you will need to use repeatedly while using a text editor is the ability to save the buffer or the file to the disk. In Emacs, saving the file or buffer to disk is easy enough but how do you rename the current buffer or save it to different file on the disk. save buffer to…

If you have been using emacs as your text editor then one of the first things you probably want to know is how to create a new file or buffer in the editor. As with many of the modern editors, emacs has the concept of a buffer and a file. A buffer is the “object” that the editor holds on…
Most emacs distributions, at least the ones I have seen come with the toolbar and the menubar enabled. More often than not, it is a distraction and a waste of space. Also if you were planning to learn emacs the emacs way, then these definitely are not helpful. You can hide or disable both the toolbar and menubar in the…

In emacs, you can browse or navigate the buffer in several different ways and the “go to line number” feature is just one of them. The function in emacs that performs this…

There are probably several hundreds more..but as you are here you probably use emacs. Although emacs is not technically just a text editor, it does have text editing capabilities and we will consider it to be one…
Just like most, my quest for an ergonomic keyboard and mouse started one fine morning when I felt a tingling sensation in my left ring and pinkie fingers. It was not bad.
