eigene bbcodes?

[Shadowproject]

ist es möglich die bestehenden bbcodes so zu ändern dass:
- [ b ][ /b ] --> [ d ][ /d ]
tastenkombi: alt+b --> alt+d

- [ i ][ /i ] --> [ k ][ /k ]
tk: alt+i --> alt+k

- [ quote ][ /quote] --> [ z ][ /z]
tk: alt+q --> alt+z

- [ code ][ /code] --> [ c ][ /c]

- [ list ][ /list ] --> [ l ][ /l ]

- [ list= ][ /list ] --> [ l= ][ /l= ]

- [ img ][ /img ] --> [ b ][ /b ]
tk: alt+p --> alt+b

was müsste ich da ändern, wenn es geht?
