      Thanks,

      I already got notified. but the notifyCode->ch is always equals to 0

      Can you please help to explain how can I check what user is typed?

        You should read the documentation on those notifications. SCN_MODIFIED does not use the ch field, it uses the text field because the user could paste multiple characters (or delete a range of text).

        If indeed you do want individual characters only (and skip any paste/deletes) then you can catch SCN_CHARADDED notifications which does use ch.

          I want to be notified when user typed “backspace”, but maybe VK_BACK is the not correct value. or maybe it was not captured in SCN_MODIFIED/CHARADDED. any recommendation?

            SCN_MODIFIED does tell you when a character (or range of characters) is deleted, but not necessarily due to the backspace key. The modificationType will have the SC_MOD_DELETETEXT flag set.

            If you are needing to capture actual keyboard input and not just changes to the text document then you’ll have to go the subclassing/superclassing route.

              Yes,
              the BACKSPACE will trigger the notification with SC_MOD_DELETETEXT bit in the modificationType. Thanks.

              I got another question.
              Currently I bind the hotkey with the function using the menu. But is it possible to hide the menu or is there any another to link the hotkey and func?

                No it is only possible using the FuncItem struct which requires a hotkey.

                Edit: Actually it doesn’t require a hotkey, however the struct is the only way to register functions with Notepad++…which automatically show up in the menu.

                  How to response the VK_ESCAPE? currently I am binding the ESC on the menu command, it works. but I was wondering whether I can filter the VK_ESCAPE somewhere or I can dynamically bind it as a hotkey for a function.

                    As far as I know you can’t dynamically bind shortcuts.

                      Hi Dali,
                      I was trying to intercept the user typing by receiving the notification when editor is read-only, so far, it works good. but read-only editor is not an ultimate solution, I wondering is there any way to ignore the key press on the editor and interact with the key pressing?
                      Regards,

                        I’m not sure. I’m not saying it is impossible though, just don’t know how.
