I'd like to remap
CTRL+(Left,Right,Up,Down)
to
Begin,End,PgUp,PgDown
And i've to say that i almost succeded, but probably there's a better way.
For the tty, i made a modified it.map.gz called itCtrlArrows.map.gz,
put it into /usr/share/kbd/keymaps/i386/qwerty/
modified /etc/vconsole.conf accordingly and rebooted.
Ttys works, fine.
For Xorg i've had to use xbindkeys with something like:
"xvkbd -xsendevent -text '\[Home]'"
m:0x14 + c:113
Control+Mod2 + Left
"xvkbd -xsendevent -text '\[Shift]\[Home]'"
m:0x5 + c:113
Control+Shift + Left
"xvkbd -xsendevent -text '\[End]'"
m:0x14 + c:114
Control+Mod2 + Right
"xvkbd -xsendevent -text '\[Shift]\[End]'"
m:0x5 + c:114
Control+Shift + Right
"xvkbd -xsendevent -text '\[Prior]'"
m:0x14 + c:111
Control+Mod2 + Up
"xvkbd -xsendevent -text '\[Shift]\[Prior]'"
m:0x5 + c:111
Control+Shift + Up
"xvkbd -xsendevent -text '\[Next]'"
m:0x14 + c:116
Control+Mod2 + Down
"xvkbd -xsendevent -text '\[Shift]\[Next]'"
m:0x5 + c:116
Control+Shift + Down
It works too, but it is an highly inefficient solution.
The tty keyboard layouts are really easy to hack, could this one be done somehow with an xkb keyboard layout?
How?

I was just trying to figure this out myself and got to the realization that keyboard layout handling in Linux == crap and total mess.
xvkbd doesn't really works as you expect, try for example your mapping in Epiphany or Nautilus.
From what I gather you really can't map key combination with CTRL to a keysym in X as CTRL isn't a modifier key.
What you can do is to set a modifier key and the best way to do that would be to patch xkeyboard-config (I didn't tried yet, just looked in the code) but if you only got one keyboard layout then you can also use xmodmap and of course both method won't work in Wayland.
See
http://cgit.freedesktop.org/xkeyboard-config (notice in symbols/us that English (US) layout doesn't map ALT_R to ISO_Level3_Shift, "level3(ralt_switch)" )

If the windows key is a modifier, i could use it instead of CTRL.
Btw, are you sure CTRL isn't a modifier key?
I'm not sure what the following output actually means.
(-pm = print modifier map)
# xmodmap -pm #(print modifier map)
xmodmap: up to 2 keys per modifier, (keycodes in parentheses):
shift Shift_L (0xa), Shift_R (0xb)
lock
control Control_L (0x8), Control_R (0x9)
mod1 Alt_L (0xe), Alt_R (0xf)
mod2
mod3
mod4 Meta_L (0xc), Meta_R (0xd)
mod5
However i can't figure out how to use it to achieve the desidered result (with the Win or the CTRL key)
-EDIT-
My example seems to work in dolphin and kwrite (i use kde) and firefox too to me.
If it doesn't for you, maybe is because your keycodes are different (i'm an it keyboard)

...meanwhile i found a daemon called bkeyd which seems way lighter than xbindkeys (at least in terms of memory, it uses almost 100KB vs almost 3MB).
It is in aur, and probably can also replace acpid with a little work.
-EDIT-
nope, bkeyd and shkd (similar tools) both uses less ram than xbindkeys, but unfortunately are more cpu hungry, with spikes even when unconfigured keys are pressed.
