Emacs Macros and the Power-Macros Package
When you have defined a number of macros, you might want to perform various functions to manage your macros. This is done by pressing CTRL-c m. It will bring up a buffer like:
the one shown in Figure 1.
What you see in this buffer is your power-macros, each separated with a line of dashes. Many keys have special meanings in this buffer (just like the keys have special meanings in the buffer-managing buffer or in the dired buffer).
Pressing the ENTER key on top of one of the fields allows you to edit the given field. Editing a field means either to change its content or copy the macro to a new one with the given field changed. You specify whichever of these meanings you intend, when you have pressed ENTER on the field.
Deletion of macros is done in two steps. First, you mark the macros you want to delete, and next you tell Emacs to actually delete them. If you know either the buffer-managing buffer or dired-mode, you will be familiar with this two-step process.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
