Description:
There is an issue in the iOS app regarding how (e.g.) charts are handled.

The use case is: a user inserted a chart and wants to edit the data source.

In this case, the user needs to know, that "single click" and "double click" on an already inserted chart has different meanings.

Single click behavior on a chart with a mouse in "Online":
- Insert a chart
- Single left mouse click on the chart so the chart has the focus
- Single right mouse click on the chart -> the "Collabora Mobile" context menu is shown (Internal cut, Internal copy, ...)

Double click behavior on a chart with a mouse in "Online":
- Insert a chart
- Double left mouse click on the chart so the chart has the focus
- Single right mouse click on the chart -> the "LibreOffice" context menu is shown (e.g contains "Data Table..." function)

The problem here is:
* we don't have "right click" in a touch only environment
* a user should not need to know that there is a semantic difference between a single or a double click

My proposal is:

Introduce "action buttons" for certain objects which are only shown when the object has the focus. So e.g. if the user taps on a chart, the chart gets the focus and one (or more) action buttons are shown. For charts, e.g:
* Chart Type
* Data Table

See the attached "mockup" to get an idea.

Steps to Reproduce:
1. Insert a chart in the iOS app and try to edit the data source


Actual Results:
There is no way to reach the dialog where the data source can be edited.

Expected Results:
There should be a way to reach the said dialog by only using a finger.


Reproducible: Always


User Profile Reset: No
