These keyboard layouts were designed to facilitate typing Dyalog APL in that they provide easy access to all Dyalog APL symbols and allow the typing of all valid Dyalog APL identifiers. As a sideeffect, they allow the typing most major Western European languages.

You will want to uninstall the Dyalog IME if you've installed it:

• Run the Dyalog APL uninstaller
• Untick "Uninstall the Dyalog interpreter"
• Hit Uninstall

These are mostly the same as the tab-input compositions found on TryAPL. See the list of symbol compositions.

This layout implements APLX's Standard (classic) APL layout for US English. Differences are:

1. It only allows using AltGr (right side Alt) for lowercase etc. APLX does the same by default, but has an option to use (left side) Alt.

2. When installed, it becomes just another national language keyboard, so it will affect all applications, not just APL. However, Windows has an option to set layout per application.

3. There are mappings for symbols used in Dyalog but absent on the original layout:

   AltGr+Shift+	Symbol	Notes
   /	⍠	default Dyalog location
   J	⍤	default Dyalog location
   P	⍣	default Dyalog location
   Z	⊆	default Dyalog location
   6	^	corresponds to normal US-EN location
   Q	⌸	"Quay" for "Key" (K is taken by a duplicated ⌷ for some reason, even though L is available)
   A	@	"At" (2 is taken by ")
   S	⌺	"Stencil" (⋄ is taken by £)
   C	⍨	"Commute" (T is taken by ⍬)

The script kbd.dyalog is a function to generate pictures of layouts. Usage:

1. ]Load path/kbd
2. kbd 'path/altgr.klc' (optionally a left argument can specify the number of keys; 101 or 102)

Build using MSKLC, which works fine on Windows 10, despite its documentation. It is safe to ignore the build warnings. Then use the generated executable to install the layout.

Note: you may have to enable .NET 2.0 and 3.5 for MSKLC to install and run. Search the web for how to do so.
