Text editing has currently some bugs in LC-HTML5 (instead use the textarea to type UTF8-text and then use 'importText'):
• Don't use option/altKey in Firefox or the standalone will hang.
The option/altKey doesn't work for editing in Safari/Chrome/Opera.
• The spacebar on Safari/Chrome/Opera takes the focus from the field,
on Opera the delete key doesn't work.
• ExportText involves some encoding problems with UTF-8.
