You was faster then I, with updating of history of changes

2) what about
2) When Help system uses integrated browser...
. Should be fixed.
5) was fixed, but then lost when I merged source code

Whould fix once more.
now about new bugs:
1) Ctrl+F1 is default shortcut used by to open syntax dependent help. Check Help->Syntax Help->Manage Help. And because syntax is not always available (defined not for every syntax), it is not possible to disable selectiong of it in keyboard settings. The same true and for shortcuts for syntax dependent templates. And in addition syntax help and templates shortcuts have priority against of keyboard map. Can you tell me for which language you have used Ctrl+F1? HMTL?
A would think what possible to do, but for now dont have an idea.. Only to disable Ctrl+F1 for selecting, but you any way would have problems with another shortcuts defined global or for some syntax...
And about
Also here Keyboard Map displays "{" instead of "F12".
. I know thi problem, but for now have not solved it, it requre to adopt xslt procesing done on xml of schema my browser. But it could not be solved for all cases, because xslt has no knowledge about current keyboard layout for example, and it can work only for one keyboard layout completely correctly. But I owuld check at least for function keys..
2) Generally it is not possible to set ANY scale level. Because scaling done based on font size. And if you have font size 10 pt, you could not get 75 or 11% for example. That is a reason for 25-20, 75-70, but 150-100 is strange... And for user defined, maybe I can add dialog called from status menu to set it.
3) Yes, it is not possible for not monospaced fonts because selection is done in chars any way, but not in pixels. So such corruped rectangle is Ok. Maybe I would think for beautify colum,n selection, but not in near feature.
4)
add "Preferences"
you mean current syntax settings you can call with context menu on overview margin? Generally possible.
Best regards,
Alex.
