Other OS US Keyboard Layouts

Amiga Style (Original)   KLC Source File    Layout Image 1   Layout Image 2
    A close re-creation of the Amiga layout, using AltGr+key for the Alt+key combinations.

Amiga Style (Extended)   KLC Source File    Layout Image 1   Layout Image 2
    Amiga-style, but with additional characters and dead keys added.

McKeyboard   KLC Source File    Layout Image 1   Layout Image 2
    A MacOS/BeOS layout, using AltGr+key for the Option+key combinations.

AfterKey (Standard)   KLC Source File    Layout Image 1   Layout Image 2
    Based on the layout of the NeXT keyboard 1991 NeXT User's Reference, using AltGr+key for the Alt+key combinations. Dead keys marked on the layout in the manual which had no associated letters in the NeXT character standard mapping or Symbol font were not made dead keys in this version.

mac.style.reg
    Not a keyboard file, but a Registry change.  Maps the left and right Ctrl keys to the left Alt function, the Windows keys to the AltGr function, the Alt keys to the Control key function, and the generally-useless Menu key to the Windows key function.  Why?  That moves the control key, used in combinations like ctrl-c, to the keys bordering the spacebar, where the Mac's equavlent Command key resides, and it moves the AltGR key to the next keys out, where the Mac's equivalent Option keys reside.
    Accordingly, with this registry change, someone used to the Mac key positions for combos like command-c and option-e can use the same physical locations on his Windows PC.

ASR-33   KLC Source File    Layout Image 1   Layout Image 2
    Approximation of the keyboard of the ASR-33 Teletype. All caps, bit-paired. Uses the correct bit codes for Shift-O and Shift-N instead of the Unicode left arrow and up arrow glyphs.

Pseudo VT320   KLC Source File
    Based on the U.S. edition of the VT320 keyboard. Compose, character, character combinations are approximated by AltGr+character, character; you cannot release AltGr before typing the first letter and must do so before typing the second. Invalid combinations will produce text rather than nothing. Covers both MCS and Latin-1 character sequences.

United States Mirror    KLC Source File   Layout Image 1   Layout Image 2

US (Symbol CapsLock)    KLC Source File    Layout Image 1   Layout Image 2
    Generally standard US layout, but when CapsLock is activated, the number and hyphen keys type various useful symbols.

    Not a keyboard layout, but a Registry change.  Makes the menu key a right-alt key, and the right-alt key a left-alt key.  For keyboard layouts that use AltGR, effectively allows you to have two alt keys in the customary U.S. keyboard positions, while making the Menu key the AltGr key.
