All of these autohotkey entries work fine:
:r0*:uuu::[url=][/url]{LEFT}{LEFT}{LEFT}{LEFT}{LEFT}{LEFT}{LEFT}
:r0*:hhh::[h][/h]{LEFT}{LEFT}{LEFT}{LEFT}
:r0*:iii::[i][/i]{LEFT}{LEFT}{LEFT}{LEFT}
:r0*:bbb::[b][/b]{LEFT}{LEFT}{LEFT}{LEFT}
But this one does not work, apparently because of a conflict with the "::" that I am trying to output:
:r0*:shh::qdev::show();{LEFT}{LEFT}
since this works with only one colon:
:r0*:shh::qdev:show();{LEFT}{LEFT}
But how can I e.g. escape the colons so that I can have a double colon in the output?
