Subject: Support selection mode
X-Git-Tag: accepted/tizen/unified/20170711.181140^0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c0b4246a61921d0bce20fc729a0d9764cca72811;p=platform%2Fcore%2Fuifw%2Fe-mod-tizen-screen-reader.git

Support selection mode

Double tap & hold with two fingers to enter the Selection mode.
If the text input filed is changed to selection mode, then we do not use two
fingers to scroll. The two fingers gesture is used as below:

 - 2 fingers flick down: select all
 - 2 fingers flick up: copy
 - 2 fingers flick left: cut
 - 2 fingers flick right: paste
