Hi Guille. Yes, some months ago I discovered that changeset. I separated it, saved into a .ch, loaded it into a PharoCore clean image and I tried to understood it. My knoweldege about Morhpic is very limited, but the changed looked of for me.
What would be cool is to commit to inbox such changes. Create an issue like "*support various focus holders for **HandMorph *" Then, send a separated mail about this changes and get feedback. If agree, we can integrate it in the core. With this, at least Algernon doesn't have to do such hack.
I also asked this to Romian as he was developing WorkingSet and the problem was that you couldn't have both at the same time because of the shortcuts. These changes may solve that. Although he didn't have time to look at it.
Cheers

Hi, i was looking at this issue and I have some questions :):
- There are some changes to HandMorph in a changeset hardcoded in the ConfigurationOfAlgernon. As Mariano said here ( http://forum.world.st/Putting-Algernon-and-WorkingSet-in-a-Dev-image-td12959...) "The main change does the simples modifications to HandMorph for it to support various focus holders". Is it safe to integrate it in Pharo? If so, should it be integrated in the core Morph package? The changeset is the following:
* '''From Squeak3.7gamma of ''''17 July 2004'''' [latest update: #5985] on 9 August 2004 at 7:56:10 pm''! "Change Set: MultipleFocusHolder-hpt Date: 9 August 2004 Author: Hernan Tylim
This changesets does the simplest modifications to HandMorph for it to support various focus holders.
The important changes are:
* addiionalKeyboardFocuses instance variable was added with its getter and setter methods.
* HandMorph>>sendKeyboardEvent: was changed to traverse the list of keyboard focus holders and call HandMorph>>sendEvent:focus:clear: to each one of them.
* HandMorph>>sendEvent:focus:clear: was changed to preserve the ''wasHandled'' status of the event, before that info were lost because the Event instance were copied before passed to the Morph. "!

It should be nice someone who knows well morphic checks it.
