[Lazarus] lazarus Digest, Vol 201, Issue 10

[Tony Stone]

Not sure if i am using this mailing list properly but I want to share my 
modified mouseandkeyinput package with the user who was having issues.  
It can be found here and I did make some "improvements" and maybe it 
will be helpful to you.

I have been using it in my password manager to automate fillign out 
forms and it works pretty good so far on windows and linux.  I am unable 
to work on any MacOS system.
