Emacs Minor Mode Sticky Control - emacs

Is there a minor mode in emacs that attaches a Control Key to every keystroke representing a single character? I wanted to get something similar to action mode in Vim. I've seen Viper, but would prefer not to spend the time to relearn all of the key-bindings.

Take a look at https://github.com/chrisdone/god-mode
This is a global minor mode for entering Emacs commands without modifier keys. It's similar to Vim's separation of commands and insertion mode.
The difference between this and viper/vimpulse/evil is that god-mode is still using the standard Emacs bindings.
It's not a direct answer1 to your question, but I think it implements your actual end goal.

Movement in Emacs using a Space-Modifier

Setup: I am running a fairly vanilla version of Emacs Prelude after I quit using Spacemacs some days ago (mainly because the usual evil-mode-incompatibities were grinding my gears).
Problem: I am having issues with the Emacs' movement commands, in particular because I am already getting a bit of an 'Emacs Pinky'. My current workaround is using modalka-mode with h/j/k/l bindings. What I would love is a direct mapping of <SPC>-h/j/k/l to the corresponding Emacs commands C-b/n/p/f. This would require the space-key to be some sort of modifier when held down. Is my desired behavior achievable in Emacs, and if yes, how?
Remark: I do not want to use evil-mode, since I found the incompatibilities with other packages to be overly annoying.
If I understand your question correctly you are looking for mode called "space-chord".
It is installable with melpa or here:
https://www.emacswiki.org/emacs/space-chord.el
You might want to look into key chords also:

They are awesome, especially with evil mode. For example I have "jk" bound to normal mode instead of escape or C-[.

Some shortcuts don't work on emacs beginning with C-c

In Haskell-mode, the shortcut C-c C-= is defined to do something.
Trying this shortcut, I realized that emacs do not recognize the shortcut C-c C-=.
Indeed, when I try the shortcut on emacs, the buffer write C-c = is not defined although I pressed C- C-=. I have the same problem with some other symbols like '.' or '§'. But shortcuts like C-c C-l or C-c C-c work.
I try to remove my .emacs but I have the same problem.
a friend have the same problem as me.
Both we are on ArchLinux (64 bits) and we use emacs in console. The keyboard is an azerty.
The problem come from emacs ? Arch Linux ?
Your terminal can't send Emacs C-= so you can't use that key sequence. (Emacs would recognise it if it received it, but that won't happen.)
Your options are:
Run GUI Emacs.
Use M-x name-of-command RET (for whatever command is bound to the key sequence you're not able to use). Use C-hm to see the major mode's bindings, or C-hb to see all current bindings, in order to learn what those command names are.
Create new custom keybindings for the commands in question (i.e. bindings which your terminal can send to Emacs).
Find a different terminal emulator with enhanced key sequence abilities. The vast majority of them will be no better than what you have, because they're all adhering to the limitations of the terminals they're emulating. The most capable one I know of is http://invisible-island.net/xterm/xterm.html but you may need to compile it yourself, and then expect to spend lots of time configuring it. (It's not a trivial solution, though, and xterm requires a GUI environment, so running GUI Emacs is much simpler.)
Use C-x#c<key> instead of C-<key>.
With that last option, you can use a sequence your terminal can send to fake a sequence that it can't send.
C-cC-= would become C-cC-x#c=
If you really wanted to use that last option, you can set a custom binding to simplify the sequence (may be necessary in some instances to avoid conflicting with existing sequences). See the end of https://stackoverflow.com/a/24804434/324105 for more information.
To add to phils' post - another option is an Emacs package (which I wrote), which can teach Emacs and terminals how to properly recognize all PC keyboard keys and modifier key combinations:
https://github.com/CyberShadow/term-keys
The default configuration already includes encoding key combinations like Ctrl=, as well as similar variations.

call emacs commande automatically

I would find a way to execute the commands in the file emacs. Emacs and therefore automatically.
For example I often use: highlight-80
So I'm forced to type every time: Meta key + highlight-80 +-fashion
it's the same with linum-mode and plenty of other.
I have been trying to put in the file emacs.:
(highlight-80 +-mode)
But the option is not enabled.
Thank you in advance for your help. I am looking desperately for a moment, emacs is my working tool quotidient.

Use C-h f or C-h v, and read the Emacs manual about such choices.
Some of them are user options (variables), whose values you can customize, using M-x customize-option, so the default setting becomes what you want.
Others are modes, which you can call/set in your init file (~/.emacs) --- see the Emacs manual for how to do that. Typically, you use a positive number to turn a mode on and a negative number to turn it off. E.g.: (menu-bar-mode -1) in your init file turns off the use of a menu bar.
In sum, the Emacs manual (C-x r) is your friend. Sit down and have a first chat with it.
You seem generally a bit unsure about how customising Emacs works, so reading the manual on this topic should probably be your next step:
http://www.gnu.org/software/emacs/manual/html_node/emacs/Customization.html
If you are not using the current stable release (Emacs 24.3 at the moment), there's a chance that some of that information will not apply. The in-built manual is, of course, always correct for the version you are running:
C-hig (emacs) Customization RET

Why isn't return bound to newline-and-indent by default on emacs

I have tried emacs on and off for a while now and every time I start emacs, I go through the same routine. Customizing. The first one is binding return to newline-and-indent. (g)Vim does this by default. Showing matching parenthesis is also done by default on (g)Vim. It is grea that I can customize emacs to my heart's content but why doesn't emacs have nice and easy defaults? For reference, I am now using Emacs 23 on a RHEL5 box.
Probably because RMS didn't want it, that and because changing long-standing defaults is just an issue of politics. Like vi, Emacs has a hard-core following and basic changes like these are minefields.
Note: if you saved your customizations, then you wouldn't have to re-do them every time...
To have those nice and easy defaults, install Emacs Starter Kit. It enables by default a bunch of useful and convenient features make even the advanced Emacs users more productive.
Otherwise, as TJ pointed out, Emacs Customization Mode (type M-x customize) allows you to save permanently any of the settings. You can even store them in a separate file from your dotemacs―(setq custom-file "~/.emacs-custom.el")―so you can use it in every computer you work on.
The title of your question doesn't really reflect what your question is (and has been answered by Trey and Torok), but I'll tell you why I like it being bound to just newline: useless whitespace. Say you are nested inside a conditional in a function etc. and hit return a couple times to leave a blank line. The blank line now has a bunch of space chars on it. Yes, you can (and I do) remove trailing whitespace before saving, but I also have visual whitespace mode on and I can see it there taunting me.

Make Emacs less aggressive about indentation

Emacs reindents the current line whenever I type certain things, like ";" or "//". This is pretty annoying, since there are a whole lot of places where it isn't smart enough to indent correctly.
How do I disable this feature? I still want to be able to indent the line with TAB, but I don't want any source code I type to cause it to reindent.
(I'm using Dylan Moonfire's C# mode, but this probably applies to any cc-mode.)
Try running c-toggle-electric-state to turn off the electric action of these characters.
You can do this as part of a c-mode-common-hook, or toggle the state manually by hitting C-c C-l.
most likely caused by the inline-and-indent 'feature' of c-mode and derivatives. emacswiki has several solutions.
