Using CTRL +V in Mail app on Mac Os X I'm using Mail client that's built-in into the system (Yosemite). I've decided that I want to use CTRL+V, CTRL+C and similar instead of CMD because I work half of the day with Windows and it's impossible for me to easily switch off my habits every half a day. I've considered 2 options:


final switch between CTRL and CMD which had a lot of consequences that I didn't wanted to tackle
switching on Shorcuts option available at System Preferences -> Keyboard -> Shortcuts and adding here any "special" shortcuts on per app basis. 


I've used 2nd option. This generally works fine. I've added things like Copy, Cut, Undo Paste and so on mostly mimicking what I have on my Windows machines. And everything seems to be working fine except one small detail "CTRL+V" paste. It only works as a PASTE until the email I'm creating fits on page. When there's a lot of text.. the CTRL+V becomes Page Down button. It's like CTRL+V in the Mail app is hardcoded to be Page Down and the shorcuts seems to be working fine until CTRL+V is able to actually behave as Page Down then it stops working. 

How do I disable Page Down (CTRL+V) behaviour as described above?
I run into same issue: At work I have to use Windows and at home I use a Mac. I'm sick of having different shortcuts for these basic tasks. Here is my solution for it:

Go to your User folder on your Mac and open the Library directory.

Here you create a "KeyBindings" folder.

Then navigate into that folder:
(Your User folder)/Library/KeyBindings/

Create a file "DefaultKeyBinding.dict" with following lines:

"^v" = "paste:";
"^c" = "copy:";
"^x" = "cut:";
"^z" = "undo:";


Save everything and restart your Mac.

Now, you will have CTRL + x/c/v/z working like it is on a Windows machine.

This will change the behaviour for page down as requested by MadBoy.
