I'm a touch-typer, then I feel bother inputting each letters
with a finger touching on virtual-keyboard of smartphone.
 
At first, I connected USB keyboard to the smartphone, but it
made another problem that cannot type when charging. So at last,
I bought a Bluetooth keyboard.
 
I've expected almost functions can use from keyboard like
Linux or Windows, but it was disappointed. Although connecting
keyboard, several operations must touch the smartphone panel.
That means I must leave off my hand from the keyboard.
Finally, just a little bother.
 
Nevertheless, it's pretty good typing with 10 fingers than one.
This document introduces the list of the functions assigned
key-shortcuts in Android I saw.
● The Legend
- [Win]……Windows logo key.
 - [App]……Application menu key. 2-4 right next key from space bar.
 
● System use
 These key operations are always available.
 
I recommend to remember [Win]+[/] key operation that show the
list of key shortcuts available. But it doesn't show all of follows.
- HOME (center ⚫ button)……[Win]+[ENTER]
 - BACK (left ◄ button)……[Win]+[BS](Backspace)
Also hiding menu or virtual keyboard on screen. - Application change (from the latest)……[Alt]+[TAB]
 - Application change (reverse)……[Shift]+[Alt]+[TAB]
 - Notice (=swipe down from above)……[Win]+[N]
 - The list of key-shortcuts available……[Win]+[/] (Slash)
Toggle: disappear the 2nd time. - Change keyboard language (IME)……[Shift]+[SP] (Space)
 - Next focus……[TAB]
 - Previous focus……[Shift]+[TAB]
 
 I wonder why isn't HOME showed by [Win]+[HOME] operation.
And why isn't the list of keyboard shortcuts showed by [F1] like
"HELP" with some modifier keys. I cannot understand the design
sense of the Google Android developers well.
 
In Japan locale mode, HOME operation is described as 自宅 (Jitaku)
means "living house", in the list of key-shortcuts. That's true,
but I could not get to understand it several hours. So I cannot
understand the design sense of the Google Android developers well.
