text field - when selecting text field to edit its content, the whole content of the field is selected, it is:

• counterintuitive: seldom the whole field's content is deleted, more often it is modified
• duplicates system functionality (select all)
• cumbersome: danger of inadvertently erasing it with one keystroke, necessary to deselect it to be able to modify it

calculation field: long tap selects the whole content, again:

• counterintuitive
• duplicates system func
• cumbersome

please modify it!
