Hello,

As discussed on october 2021, I tried to add NO_XXX, XXX = {CONTROL,LSHIFT, RSHIFT, ALT}

to ST modifiers.

With hatari (git master) + enhanced_keymap_patches.tar.gz +emutos512k-1.1.1 (fr)and the following mapping, the '§' key on PC side gives the '§' key onST side :

0x38|SHIFT,0x07|NO_LSHIFT|NO_RSHIFT

Previously, the key was mapped by :
0x38|SHIFT,ALT_XXX|221

I suppose the patch '0014-Add-NO-XXX-mod.patch' miss a lot offunctionnal requirementsand could cause various bugs as I do not understand the whole code inkeymap.c and ikbd.c.



In attachment, you'll find the files :

1) enhanced_keymap_patches.tar.gz which contains all patches to apply tomaster.

2) keymap_fr_pc_no_xxx.cfg which contains mapping.

#-------------------------------------------------------------------------------
# Mapping Format :: Host (PC) key definition , Guest (ST) key definition
#
# Key definition :: scancode | modifiers
# or (host only) :: keyname  | modifiers
#
# Host key definition is separated from Guest key definition by a comma ','.
# scancode or keyname and modifiers (several possible) are separated by a
# pipe '|' and may be interverted.
#
# Scancode is decimal or hexa (prefixed with 0x)
#
# Host modifiers are  : LSHIFT (Left Shift),
#                       RSHIFT (Right Shift),
#                       SHIFT (LSHIFT or RSHIFT),
#                       LCTRL (Left Control),
#                       RCTRL (Right Control),
#                       CTRL (LCTRL or RCTRL),
#                       LALT (Left Alt),
#                       RALT (Right Alt / Alt gr),
#                       ALT (LALT or RALT),
#                       LGUI (Left Windows),
#                       RGUI (Right Windows),
#                       GUI (LGUI or RGUI),
#                       CAPS (Caps Lock),
#                       MODE (Menu),
#                       NUM (Num Lock).
#
# Guest modifiers are : CONTROL,
#                       LSHIFT,
#                       RSHIFT,
#                       ALT,
#                       ALT_XXX,
#                       NO_CONTROL,
#                       NO_LSHIFT,
#                       NO_RSHIFT,
#                       NO_ALT.
#
# ALT_XXX is a special case where ST scancode is the decimal code
# (32 to 255) in atari character table.
#
# NO_XXX modifiers disable corresponding ST modifiers.
#
# Empty lines are ignored.
# lines beginning with a hash '#' or semicolon ';' (comments) are ignored.
#-------------------------------------------------------------------------------
# Keys are mapped in Host scancode order. If a SAME Host scancode
# is mapped multiple times, the associated modifiers must be ordered.
#
# For instance, a PC host scancode with three possible modifiers
# mod1, mod2, mod3 must be configured (Host key definition) like this :
#
# scancode|mod1|mod2|mod3     (1)
# scancode|mod1|mod2          (2)
# scancode|mod1|mod3          (2)
# scancode|mod2|mod3          (2)
# scancode|mod1               (3)
# scancode|mod2               (3)
# scancode|mod3               (3)
# scancode
#
# Line marked (1) (3 modifiers) must be first,
# Then lines marked (2) (2 modifiers) in any order,
# Then lines marked (3) (1 modifier) in any order,
# Then line marked (4) (no modifier) must be last.
#
# This is because Hatari search the first definition where :
# input scancode = entry scancode
# and
# input mods and entry mods = entry mods.
#
# If entries are given in this order :
#
# scancode|mod1               (1)
# scancode|mod1|mod2          (2)
# scancode                    (3)
#
# and input is scancode and mod1 and mod2
# the entry used by Hatari will be (1) because
# input scancode = entry scancode
# and
# (mod1 and mod2) and mod1 = mod1.
#
# The worst order would be to place scancode without modifier entry
# before same scancode with any modifier entry because
# any modifier and no modifier = no modifier.
# The user could no longer use any modifier key for this scancode.
#-------------------------------------------------------------------------------
# Comments before mappings show guest symbol obtained when key and
# given modifiers for host symbol (french keyboard) are entered.
#-------------------------------------------------------------------------------
# REMEMBER : 
# 
# 1) Any host scancode or keyname not mapped here defaults to
#    symbolic keyboard mapping (corresponding to TOS language)
#
# 2) Hatari uses shortcuts to specific functions in keyboard
#    setup and number of these shortcuts use RALT modifier.
#    So, you must remap the key used by Hatari if you want use
#    it in your mappings.
#
#    Example : Hatari maps 'g' + [RALT] to 'take screenshot' shortcut.
#    If you want to use 'g' + [RALT] in your mappings, you must map
#    another key than 'g' to 'take screenshot' shortcut.
#
# 3) Mappings defined here have been tested with a french PC keyboard
#    (105 keys) and with French and USA TOS. They all produce expected
#    characters (and display expected symbols) on Hatari screen.
#
# 4) Guest key definitions using ALT_XXX disable auto-repeat.
