how due i do a mouse over on an I phone 6

Hi its Carlos,
I have a few sites that require mouse over to drop down links with in a list.
In jaws i would press control plus insert plus enter and it would say text changed,
and the links in the list would apear.
I have seen the links drop on the i phone but don't know how it happened.
I do not use a blue tooth key board so I would like to know is there a jester to preform this.
I am thinking of buying a blue tooth key board maybe from AT guys but haven't yet.
Any help would be greatly appreciated.
Thanks
Carlos
