Are there any custom keyboard available for laptops

Solution 1:

I'm not aware of anything like that. Laptop keyboards are highly proprietary parts, designed for each particular model, sometimes with additional features like backlighting, tracpoint, liquid drain channels, custom Fn-hotkeys, etc. It doesn't make financial sense for laptop makers to offer multiple keyboard layout options, and it just isn't feasible for any third-party manufacturer to offer custom keyboards for all existing laptop models. I'm afraid you're stuck with what you have.

If you want a 15" laptop with standard arrow and navigation keys and no numpad, check out the ThinkPad W5x0 series (W520 and W530 are the latest models).

Solution 2:

You will be very lucky to find a complete replacement keyboard that suits your needs.

You could probably pay for one to be made, but it wouldn't be cheap!

Or another option (used by many users) is a custom keyboard layout. This will change the function of certain keys to be whatever you need, obviously without changing the actual keyboard key tops themselves.

Information on SOF.

Keyboard Layout Editor.

Further information regarding regional layouts.

You will find lots of information about this when you start digging around... Many small countries and different subsets of languages will have people who have custom layouts for specific characters even when using a 'western' style keyboard. Remapping certain keys to others (ie exactly what you wish to do).

Looking at the image you've added to your original question. You can clearly see 'Arrows' on the numberpad keys (2486) and Home (on 7), Pg Up (on 9), End (on 1) and Pg Dn (on 3). So just turn Num Lock off? (key above 7.)

Providing this is exactly how your keyboard looks then you have a solution already!
