Emacs remember text selection -

I have decided that after some years of using GEDT for some of my coding needs, Trying to try Emacs, I knew it would be difficult, as I have heard how complex MACS can be, but I'm greedy with its power. To change things about the editor, the most difficult thing is being used to write Elspe in the AMCS file. I can not do it myself at present, but I have found some useful snippets here and there to change some options.

One thing I have many problems with. I have selected after an order. For example, I usually highlight a part of the code for large-scale indent. However, if I do this in MACS, then it will move the selected text only once before selecting all the text, does anyone know a path around this?

Anyway, I apologize for what I think to be an easy question, but looking after Google search and looking around here, I thought it was worth asking. I have some more questions about Emacs, but I will save them and after coming straight out, I will ask separately. Thanks!

UPDATE

Some people have asked how I am using and what type of text I am entering. Although I do not know much about Amacus mode, but I'm currently editing a pure text file. Something like this:

  Hello, I am a simple text file that is made up of three separate lines  

If I highlight all three lines And press tab, I get this:

  Hello, I'm a simple text file that has three different lines  

This is great, however, if I use CX CX such that the text is re-researched and the tab is pressed again, then I get it:

  Hello, I am a simple text file that is made up of three different lines. I  

I hope it helps!

Try typing CX CX later

Then, instead of killing tab (I did not know that the tab did what you said! It is completely whacked.), Code> M - 8 cx ci . Mercy is a lot of keys, but you should do what you want - that is, everything is teasing on 8 columns. Clearly replace M-8 with something else if you want some other columns.
