[Lazarus] Cut, Copy, Paste shortcuts don't work in SynEdit

[Martin Frb]

the patch here might help, but might cause new issues (so I was told / I 
remember some discussion on the topic, but I cant find it)
(It is very old, not sure if the issue is still the same)


The issue is that the "time" in the events for different keys is the 
same. Apparently that means it is one event only (again Ive been told, I 
never looked at the gtk spec)

The LCL filters by that time.

the patch adds the key itself to the filter.
But if you take a key that is currently handled correctly, and where the 
"key" value is changed by a handler, then the patch will lead to that 
stroke being duplicated (or maybe duplicated...) (again so I was told)
