I can 't really say this is a feature, but I think it's a good thing to have uniform IDE shortcuts/hotkeys. Yes, it really is a pain to set up the shortcuts to mimic what I'm used to. A few changes will end up to change the rest of the shortcuts. And most importantly, Nobody uses CTRL+F4 to close MDI documents because you need to move your finger forward and bend your hand (people hate it, believe me). The most common shortcut to close MDI documents is CTRL+W (Google Chrome implements that, Firefox implements that, Visual Studio haven't which makes me hate it).

One solution I can think of is an ability to create, export, import, and set profile of shortcuts (it'd be nice if it comes with Visual Studio shortcut profile).

I believe that most people love it when they don't have to learn and unlearn things they are used to. I'm looking forward for an answer.

Btw, English isn't my primary language. Therefore I welcome criticisms, spelling and grammar corrections.

Fill free to assign Ctrl+W instead of Ctrl+F4 for closing file, it's kind of trivial thing in PhpED
