I prefer chording: CapsLock+S+T+UNEI means Shift-Ctrl-arrows for instance. Or CapsLock+T+O means Ctrl-Backspace to delete a word. Works great with PKL Extend mode in Windows, but not yet with the X.Org server in Linux (I have arrows but not the chording modifiers).

strangely I enough I find myself using the delete a lot, and strangely enough I was thinking of finding a better position for it today, and here you are giving me a very nice idea that allows me to map 3 functions. Now I can find more space and place my mapping LShift+BS to something and RShit+BS to something . I could even extend this to map other keys especially on the right hand where I can utilize the Ctrl, Enter, etc... Thanks for the input :)

Brilliant idea, I often use the arrows due to my programming style because I usually write something like this for(){}  in order not hit the shift too many times and in order to reduce the chance of forgetting an enclosing symbol, but I pay in terms or speed reduction and the fact that I have to use the arrows to go back and fill the expression section and the body of the for loop. Now If I mapped on QWERTY Tap+CapsLock+ jckl I can emulate the arrows and there is no need to leave the center of the keyboard :). Great Now, I have new ideas, which should keep me occupied for long time... Thanks for the input :).

I think it will take me more years to optimize my keyboard :(.

Definitely, I will do something like that when I digest the changes that I have already made now. My question is that you can implement this in PKL under window? and How you do it under Ubuntu?

You mean the this pkl https://www.autohotkey.com/forum/topic28447.html ?  Or you have made your own? If so is it a compiled autohotkey script or did you use other programming languages ( C, C++, java, C#.... etc) and where have you posted it?

Finally, I have question about Microsoft Keyboard Layout Creator if you do not mind :). I have built several layouts over QWERTY with MKLC, but this time I wanted to build a layout from scratch and modify the copy paste form the standard QWERTY but it seems that  I can not do it in MKLC, or at least I do not know. I do not want to do registery mapping I just want to know if it is possibly to do it with MKLC or not?

1) Yes, PKL by Farkas Máté. My .ini for that (more or less) is here.

2) Not sure what you mean. By editing and compiling the files yourself you can for instance make the CapsLock key a Backspace or what-have-you using MSKLC - but as Pafkata says, the GUI won't let you do that so it's a question of definition whether you can or cannot do it with the MSKLC tool. Making Cut/Copy/Paste keys is possible, but they won't be supported everywhere. One thing is making a key code, another is whether your OS and programs know what to do with it!

First, a posting tip: When you post your files and suchlike, use square bracket tags (BBCode) with 'code' and '/code' around it! Looks nice, and can be scrolled and copied easily. :)

I think I see your problem. It's not about Copy/Paste/etc (my previous answer was for making actual Copy/Paste/etc KEYS which do exist but are poorly supported so they're not all that great). It's about VKEYs. That means Virtual Key codes and I see that you haven't remapped yours when using MSKLC. It's like this, abouts:
1) The keyboard sends a scan code to the computer;
2) then that's translated to a virtual scan code (which is what you can remap with the "registry method";
3a) then that scan code (the first column in the main part of the .klc file) is linked to a virtual key code (which is what your Copy/Paste hotkeys usually uses!) and
3b) at the same time an input event may be created sending a glyph to the input stream depending on the current modifier state (shift, ctrl, lvl3/altgr, SCaps if defined...).
4) In most cases, only the Shift and AltGr states are used for glyph events although there are some exceptions for Ctrl in some layouts (you don't want to abuse that as Ctrl combos are better used for actual control events as you're familiar with - such as Copy/Paste/etc you know...).

This you can fix in the GUI! If you want a key to send, say, the letter X and you also want the key to work with Ctrl-X for Cut then you need to set the VK_ for that key to X and not just the glyphs it produces! You'll find out how, it's there in the GUI for the keys.

Or you could actually edit the .klc directly, replacing the VK_ keys. Then when you open the file in MSKLC it'll work (unless you did it wrong, hehe). Whatever is best for you.

Caveat: Some silly programs will not use the VKEY code as they're supposed to, but sniff for scan codes directly. Then they'll be using the "QWERTY" hotkeys no matter what unless you registry remap. Silly, silly programs - that's bad form but it has been seen.

I solved the problem by editing the VK_ keys in the source file and I was able to map backspace to [ in the file also, but I guess I have to do the other modifiers mapping through the registry using keytweaks or sharpkeys. I have actually learned a lot the last two days about scan codes. I used to think that there is only one set but it turned out that there are actually three :).

Indeed, you should not mess with scan codes in the GUI and the .klc file. The scan codes only denote the keys or ( the hardware) and if you want to change which character is assigned to key you just change the the pressed state and shift state in column 0 and 1 and the VK_ (for ctrl+character to work properly). I found the following links very helpful and almost comprehensive on this subject.http://www.quadibloc.com/comp/compint.htm

Now, I have to do the mapping in ubunto, and I have to search on that too :8.
