Google will initially be focusing on smartwatches that can provide notifications, answers to voice searches, health and fitness monitoring, connections to devices, and anything else developers can create. As with Android, Google will be working with other companies to develop watches powered by Android Wear in 2014. follow link
Avoid Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
