UP and DOWN are really needed.
Hope the extra keys can be configurable.
or, swipe right to show more keys.
because of the lack of arraw keys, I have to use JuiceSSH to edit files.
if arraw keys could be added, JuiceSSH is no longer needed.
Volume up + w = up arrow
Volume up + s = down arrow
Or use something like the CodeBoard keyboard:

@sdrausty yes,but not convenient。
Really surprised no one's mentioned Hacker's Keyboard yet:

@miho @4oo4 thx. but when i write something mixed with Chinese,i have to switch the en keyboard and Chinese keyboard witch each other。
while the Chinese keyboard can easily change to English mode by tapping a key, but doesn't have arrow keys.
@sdrausty on my pad, I have to use both hands to Volume up + w, it's too far to use single hand. 😅
I pull some code In #605, seems work fine on my phone.
@xqdoo00o well done. hope it will be merged later.
@FuckDoctors
but not convenient
On most smartphones this feature is very convenient. I can see how this feature might be cumbersome as @xqdoo00o states on large tablet, and I have run into a couple of smartphone models where I must agree with you.
These smartphone models have the volume button(s) at the back of the unit. After getting used to it, it's not as bad as at first. The bending the device's shape effect isn't too pleasant when pressure to the button is applied.
As stated, on most devices volume + key is a beautiful shortcut. Are your volume buttons at the back of the device @FuckDoctors @xqdoo00o?
@sdrausty yeah, but when editing files, sometimes need to move to big column, you have to pressed down Volume up then press d for many times.
In #605 , just need to long press right arrow key.
@xqdoo00o thanks for your time and attention. Volume buttons at the back of the device make the volume+key feature cumbersome, clunky to use.
pressed down Volume up then press d for many times.
Volume buttons at the side of the device don't need to be pressure pressed down. They are simply held in palm of hand along with device.
Are there any ideas as to why CTRL+w doesn't work, but volume button up + w which is bound to CTRL+w does work for scrolling back through BASH history?
Wouldn't it be possible to add arrow keys to the "extended keyboard" (the thing that appears when you long-press the keyboard button in the menu)? Or event better, to make it customize able (e.g. adding a ":" for vim-users)?
Hacker keyboard is better for any keyboard (anysoftkeyboard, codeboard, terminalide)
I just got myself an android e-ink tablet that has neither volume buttons nor left drawer and I can't find any way of turning on the extended keyboard. Why isn't this setting available in the long press settings menu?
