Added November 2013
The opcodes CTLOP_TABSET and CTLOP_TABCLR are used for setting and clearing the MBF_TABSTOP property of a control:
xcall AUI, AUI_CONTROL, CTLOP_TABSET, ctlid ! set MBF_TABSTOP for ctlid
xcall AUI, AUI_CONTROL, CTLOP_TABCLR, ctlid ! clr MBF_TABSTOP for ctlid
AUI_EVENTWAIT should skip over controls that do not have the MBF_TABSTOP property when using the keyboard navigation controls.
Note: the rules for auto-initializing the MBF_TABSTOP property when creating new controls are a bit vague; these opcodes allow you to be explicit.
Also note: the control dump contains a column making it more obvious which controls have the tabstop property, which show up with a numeric value of the control number offset by 5000. Currently there is no way to change this table order, which generally matches the order in which the controls were created.
