IDE improvement, IsEditableTextKey()

[AlexTP]

I suggest faster code for LCLProc function:

Code: Pascal  [Select][+][-]

1. function IsEditableTextKey(Key: Word): Boolean;
2. begin
3.   Result := (Ord(Key) <= $FF) and (byte(Key) in [
4.       VK_A..VK_Z,
5.       VK_0..VK_9,
6.       VK_NUMPAD0..VK_DIVIDE,
7.       VK_OEM_1..VK_OEM_3,
8.       VK_OEM_4..VK_OEM_7
9.     ]);
10. end;
