* Data Browser: skipping invisible column when navigating using keyboard

* Data Browser - navigating to the beggining/end when using left/right keys with modifier (ctrl/meta) key pressed

* Data Browser: taking hidden columns into account when establishing the left/right edges

* Data Browser: safety check to prevent from infinite loop

* Data Browser: updating comments
