I've found a better solution for me because the Visual Studio emulation is not the same as my VS and can't be customised
and as Altar mentioned GExperts IDE menu shortcuts is not working with Delphi XE.
Using AutoHotkey I remap the keys using this script:
#IfWinActive, ahk_class TAppBuilder
;Set breakpoint
F5::F9
;Run
F9::F5
;Step Over
F10::F8
;Trace Into
F11::F7
;Delete line
^l::^y
;Switch between form and code
F7::F12
;Find Declaration
F12::Send !{Up}
;Navigate Back
^-::Send !{Left}
;Navigate Forward
^=::Send !{Right}
;Duplicate Line
+Enter::^!+d
;Incremental Search
^i::^e
