In the short term, we should certain do that.
Could you please also file an issue in ImageJ Legacy about this bug with the text tool active? Off the top of my head, I am not certain what the best way will be to fix it in general. Design-wise in SciJava, the general idea is that active
Tool plugins which receive and act upon events have the option to consume them, so that the general-purpose shortcut mechanism then never receives the key event. Of course, the text tool is an IJ1 tool, not a SciJava tool, and we did not yet implement any sort of bridge between the two in ImageJ Legacy.
