I have created a simple plugin to provide VIM like keyboard shortcuts
The default shortcuts are:
J ---> next row
K ---> previous row
Ctrl+F ---> page down
Ctrl+B ---> page up
G ---> first row
Shift+G ---> last row
H ---> left cell in a row
L ---> right cell in a row
Shift+H or 0 ---> first cell in a row (note: the key is zero, not english O)
Shift+L or $ ---> last cell in a row
They can be overridden in Preferences->Shortcuts->Vim style:
