OpenLayers 3 : DragZoom, change shortcut from [Click + Shift] to [Click + Ctrl] -


i'm trying change default behavior of ol3 on dragzoom event: want feature, default configured on [click + shift], working instead [click + ctrl].

do have idea of how perform that?

already consulted online doc: http://openlayers.org/en/latest/apidoc/ol.interaction.dragzoom.html

seems "condition" property, can't figure out how that.

the "condition" value has function called when event occurs. openlayers doesn't come ol.events.condition.ctrlkeyonly, define own. you'd need disable default dragzoom interaction first, add own:

var interactions = ol.interaction.defaults({   shiftdragzoom: false }); interactions.push(new ol.interaction.dragzoom({   duration: 200,   condition: function(mapbrowserevent) {     var originalevent = mapbrowserevent.originalevent;     return (       originalevent.ctrlkey &&       !(originalevent.metakey || originalevent.altkey) &&       !originalevent.shiftkey);   } }));

see in action in jsfiddle demo.
