Hi Stephane,
Thank you for your interest in Syncfusion products.
I am afraid I am unable to reproduce the issue. To explain this criteria I have created a sample which makes use of action-keystroke binding functionality for command's like New, Save, SaveAs, Open and Goto. Here is the sample for your reference.
http://websamples.syncfusion.com/samples/Edit/35524/main.htmHope so my understanding is correct. If not can you please send your sample program using which the issue is reproduced which will be more helpful for us to investigate further in this issue.
Please let me know for further help.
Regards,
Sarath
