Interesting....
I'm using the CKEditor4 plugin with q2a 1.6.2.
In the :
Admin-->Plugins --> CKEditor4 ---> "Other Configuration"
I've added on top of all the other lines this setting :
scayt_autoStartup:true
that enables the Spell Check As You Type (SCAYT) embedded CKEditor4 feature.
That is I've changed the default configuration from :
toolbarCanCollapse:false,
removePlugins:'elementspath',
resize_enabled:false,
autogrow:false,
entities:false
to
scayt_autoStartup:true,
toolbarCanCollapse:false,
removePlugins:'elementspath',
resize_enabled:false,
autogrow:false,
entities:false
I've tested it on Chrome, Mozilla and IE and it works....
Thanks for tip
ps
the scayt feature is embedded also in the default q2a WYSIWYG editor, but I've not tested it
