This layout adds the danish Æ, Ø and Å symbols to the ANSI / US keyboard layout. The ANSI layout is much more convenient for programmers than the normal Danish ISO layout.
Symbols frequently uses such as {} [] are hidden in the danish layout on layer 3 in the numbers 7 - 0. The ANSI layout have them as first class citizens on layer 1 and 2 on dedicated keys. Hoever for Danish these keys are used for the accent symbols and therefore not available. So the compromise in Dwerty is to put them on layer 3 and 4 on the same keys, and for convenience also on layer 3 on o and p.
The ISO <> key next to the Z button is not available on ANSI. These sit on the , and . buttons. Also the ; and : button on ANSI is used on danish for the æ accent symbol. The compromise is to keep the danish mapping for ; and : on the layer 2 of , and ., and move <> to layer 3, as this is lesser used (pun intended) - but still keeps their ANSI position
Take a look at the layout.png if this makes sense to you. Otherwise it's easy to modify the layout text file.
This is an adaptation of the Swerty keylayout for Danish: https://johanegustafsson.net/projects/swerty/

Add the contents of se.txt to the end of the file /usr/share/X11/xkb/symbols/dk. Then look up the following section in the file /usr/share/X11/xkb/rules/evdev.xml:
<layout>
<configItem>
<name>dk</name>
....
Add the following variant block after the line :
<variant>
<configItem>
<name>dwerty</name>
<description>Dwerty</description>
</configItem>
</variant>
Finally, after the line "! variant" in the file /usr/share/X11/xkb/rules/evdev.lst add the following line:
dwerty dk: Dwerty
Now Dwerty should show up as one of the alternative keyboard layouts for Danish
Note that the screenshot layout.png shows the layout with a PC105 keyboard, while it is intended for PC104 (ansi)
