I am wondering if there is any way to have a keyboard shortcut to a tab. Like for example Firefox having Alt+1 / Alt+2 / Alt+3 to go to tab 1 / 2/ 3 etc...
Cheers,
You can use F12 to go to the current editor and Ctrl + E to get a list of open editors. Then you can type a couple of characters to narrow down the list. The currently visible tabs are at the end of the list (use End or Up to jump there)
Ctrl + PageUp and Ctrl + PageDown select the previous and the next tab.
Ctrl + Q goes to the last edit position.
Alt + Left and Alt + Right go back- and forward through your editing history (like the back button in your browser).
Also, use Alt+PgUp and Alt+PgDown to shift between graphical layout and xml code inside android graphical layout editor for xml files.
for right side move CTRL+ page Down
for left side move CTRL+page Up
