Hi Guillermo, Now TWM works with ConfigurationOfKeymapping 1.8. Gofer it squeaksource: 'TilingWindowManager'; package: 'ConfigurationOfTilingWindowManager'; load. ConfigurationOfTilingWindowManager loadDevelopment. Something I want to fix: if an editor has the focus, TWM shortcuts don't work. I've tried: TilingTWMSettings class>>buildKeyMappingSettingsOn: aBuilder <keymap> ..... {PasteUpMorph. SystemWindow. TextEditor. SmalltalkEditor} do: [:aClass| aBuilder attachShortcutCategory: #twmShortcut to: aClass ]. but no success .....
