Alt +0-9 is very destructive, is it possible to disable ALT from 2 to 0?

when you 1st launch scummVM
lucas arts game like "Indiana Jones 2" shows HELP tab between Options and About
but
non-lucas arts like "Simon the Sorcerer 1" DOESNT show HELP tab between Options and About
what would be the reason?
----------------------------------------------------
but whether it is lucas game or not, these keys STILL work for all games

F5 = menu
.

.
Ctrl + 0-9 = load
Alt + 0-9 = save -- needs to be disabled
Ctrl + F = move fast
Ctrl + Z = quit

Alt + 0-9 is very destructive, is it possible to disable ALT from 2 to 0?
the game needs ONLY one key for quicksave, i can use a MENU for the rest of game-savings with important filenames

more of my thoughts on quicksave and load
F6 as quicksave but hardcoded (so old that this key can not be remapped), example games are below
Warcraft3
Tiberian 2 - Renegade
Settlers 5
No One Lives forever 1
No One Lives forever 2
rebindable F6 quicksave
AvP2,Star Trek - voyager 2

F5 for quicksave (these games' F5 can be remapped to F6)
Unreal 2 - Awakening, prey, doom3,quake4,rage, Hard Reset - Redux, Elder Scrolls 4 -Oblivion
Starship Troopers

CTRL-S ALT-S
all DOS games and applications, Battle Realms,Dragonshard,Jagged Alliance 2,Dungeon Siege 1,Dungeon Siege 2
settlers 4

check point
bill gates HALOs, all pc pretending games of console origin

if i had a choice, i'd rather have F5 as a quicksave than F6, but F6 came as quicksave 1st and hardcoded, i DONT wanna remember two quicksave keys, so all goes to F6
BUT why would any game makers use function keys such as F5 and F6 for SYSTEM INTERFACE like save and load games

Function keys MUST be used for things like below
hero selection
battle gear (or skill)activation
various item selection
weapon and group's COLLECTIVE selection from dungeon siege
------------------------------
CTRL-S, ALT-S MUST be used for SYSTEM INTERFACE like quicksave and load games like DOS.
but in these days, game makers use function keys for saving and loading games
AND then they use a pulldown menu to change weapons and ammos and skills.... i consider these games are trash, because i can NOT change anything in 0.1 seconds, it takes 30 seconds sometimes and too tired to change often, the worst games were crysis 1 2 3
