How remap keyboard on "asciitilde layout mode"

  • 772

I'm trying currently to use the xmodmap -e function in order to remap my keyboard. I want to replace the twosuperior key with greater and less depend of the asciitilde mode being activated.

I talk about asciitilde or grave mode in reference to this convention

I wonder how remap the "asciitilde mode layout" since I retrieve the same keycode for the "grave mode layout" and "asciitilde mode layout".

Here what I retrieve with the xev process : 

// retrieving less
keycode 94 (keysym 0x3c, less)"<" 

// passing in asciitilde layout mode
keycode 50 (keysym 0xffe1, Shift_L),

// retrieving greater with asciitilde mode activated
keycode 94 (keysym 0x3e, greater)">"

 ------------------

// retrieving the code of twosuperior key 
keycode 49 (keysym 0xb2, twosuperior) "²"


// passing in asciitilde layout mode activated
keycode 50 (keysym 0xffe1, Shift_L)

// retrieving the code of twosuperior key with asciitilde being activated  
keycode 49 (keysym 0x0, NoSymbol)

As you can see I retrieve the same keycode for grave layout mode and asciitilde layout mode.

How can I make change on asciitilde layout key map ?

Thanks

  1. In fact it is very simple.

    The first argument refer to the "lowercase mode layout" and the second argument to the "uppercase mode layout", so the code syntax is the following :

    xmodmap -e "keycode [keycode_number] = grave_mode_argument asciitilde_mode_argument"

    So in our case, to put the less and greater symbols in the place of twosuperior symbol, we can just run the following code :

    xmodmap -e "keycode 49 = less greater"

    Also, we can retrieve your keycodes numbers using the [xev process][1].
