the rule of thumb
what is an easy way to know when to use está-esta-este-esto

Practice. Here, I'll share the little chart I was helping a friend with the other day.
English version more or less: This (these) - That (those) - That over there (those over there)
Esto: no specific object defined, neither masculine nor feminine
Esto (estos) - Eso (esos) - Aquello (aquellos)
Este: for masculine objects
Este ... (estos ...) - Ese ... (esos ...) - Aquel ... (aquellos ...)
Éste - Ése
Esta: for feminine objects
Esta ... (estas ...) - Esa ... (esas ...) - Aquella ... (aquellas ...)
Ésta - Ésa
This is divided by distance (esto nearest, eso farther, aquello farthest), and the plural forms are in parentheses. The last two for este and esta are used when you know what gender the object has, but do not want to actually name the object.
Here are some examples: Este zapato = Éste. Esta camisa = Ésta. Whatever = Esto.
Está is part of the verb estar, and is not related to these rules.
The little jingle I've always heard is: " 'this' and 'these' have the T's, 'that' and 'those' don't. Works for most situations.
