At the level of ToolBuilder, one would rather have to specify a "tab order" and whether such a feature is enabled for a particular view or not. It would be like one or two additional fields in PluggableWidgetSpec. No need to talk about implementation details such as "siblings" at that abstract spec level.<div><br></div><div>Considering the actual implementation: there has been a "tabAmongFields", which might origin from Etoys. In the MorphicToolBuilder, I would simply add <b>event filters</b> for keyboard events at the level of <b>PluggablePanelMorph</b> and/or <b>SystemWindow</b>. You do not have to deal with implementation details in TextMorphs etc. If "tab" would be the key, "tab" would just not reach the TextMorph anymore. :-) ... off the top of my hat ... maybe like half a day work including tests. Not many new lines of code...</div><div><br></div><div>Best,</div><div>Marcel</div><div class="mb_sig"></div>
