Moving to Next Field with the Tab Key
People who prefer to use the keyboard can use the Tab key to go to the next field.
Normally, the cursor goes from left to right and from top to bottom, so it would
travel into the fields in the Function column (more on this in a moment). However,
to ease data navigation in phpMyAdmin, the normal order of navigation has been
altered; the Tab key first goes through each field in the Value column and then
through each one in the Function column.

Moving with Arrows
Another way of moving between fields is with the Ctrl+arrows keys. This method
might be easier than using the Tab key when many fields are on-screen. For this to
work, the $cfg['CtrlArrowsMoving'] parameter must be set to true; this is the
default value.
On a Mac OS X 10.5 with Spaces enabled, Ctrl+arrows are the default
shortcut to switch between virtual desktops, so this technique cannot be
used for moving between fields.
Handling NULL Values
If the table's structure permits a NULL value inside a field, a small checkbox
appears in the field's Null column. Checking it puts a NULL value in the field.
A special mechanism has also been added to phpMyAdmin to ensure that, if
data is typed into the Value column for this field, the Null checkbox is cleared
automatically. (This is possible in JavaScript-enabled browsers.
