It seems like you are experiencing an issue where events and attachment keys are not visible in the animation dopesheet. This could be due to a few reasons. One possibility is that the bone or slot to which the keys are attached is not selected, as the timeline for slot attachments is only displayed when the parent bone is selected. Another reason could be that a filter is applied in the dopesheet, which might be hiding certain keys. You can try turning off the filter to see if the keys become visible. Additionally, ensure that the correct bone or slot is selected to display the relevant keys in the dopesheet.

Regarding your question about uploading images for reference, while I can provide guidance based on descriptions and context, I cannot directly view or refer to images uploaded here. However, you can describe the issue or provide additional context, and I'll do my best to assist you.

rmx Spinebot does not understand the contents of images very well, so it is easier to get a better answer if you explain the situation in words.

It is unclear from your screenshot because the toolbar is cropped, but if you are not applying any filters, the event keys may be hidden in the tree view. Click the visibility dot next to the Event node to hide the Events timeline.

Also, based on the information that the attachment timeline is not displayed, it is possible that the Sync button is enabled. This aligns the contents displayed in the dopesheet view with those displayed in the graph view, hiding timelines that are not necessary in the graph view.

In the following example, when viewed in the graph view, the head bone has timelines for Rotate, Scale, Attach, and Events, but since only the rotation curve is displayed, only the Rotate timeline is displayed in the dopesheet view with Sync enabled:

As such, the display content changes depending on the options selected. If you notice any issues with the editor display, please upload a screenshot that has not been cropped so that we can quickly identify the problem.

Note the event timeline is shown despite the visibility dot if the Events node or any event is selected. That can make it seem like the Events visibility dot does nothing, then only later you notice the events timelines are gone and may not remember the visibility dot.
