FREQUENCY CONVERTER WITH TEXT EDITOR
First Claim
1. A method for obtaining a symbol string user input via a four-directional control device in a frequency converter, the method comprising:
- grouping potential symbols into at least two symbol lists;
treating one of the symbol lists as a current symbol list;
displaying at least part of at least the current symbol list;
displaying a cursor indicating one of the symbols in the current symbol list as a current symbol;
receiving commands via the four-directional control device; and
based on the received commands, selectively changing the current symbol list to one of the other symbol lists, effecting relative movement between the cursor and the current symbol list, and selecting the current symbol as the next symbol in the symbol string.

Abstract
A frequency converter includes a symbol string editor in which the potential input symbols are grouped into at least two symbol lists. One of the lists is treated as a current symbol list, which can be scrolled and from which the symbols can be selected as the user input. In addition, a user is allowed to control change of the current symbol list such that the symbols in all of the symbol lists are available for selection. This arrangement allows for scrollable lists to be significantly shorter than a single list of potential symbols would be, which makes entering symbol strings faster.

6. A frequency converter comprising:
-
a data structure including symbols grouped into at least two symbol lists, one of which is a current symbol list; a display configured to display at least part of at least the current symbol list and a cursor indicating one of the symbols as a current symbol; and a four-directional control device configured to receive commands; and a controller configured to, based on the received commands, selectively effect the change of the current symbol list to one of the other symbol lists, effect relative movement between the cursor and the current symbol list, and select the current symbol as an input. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 22, 23)

16. A frequency converter comprising:
-
a data structure including symbols grouped into at least two symbol lists, one of which is a current symbol list, each of the symbol lists containing a switch lists symbol; a display configured to display at least part of at least the current symbol list and a cursor indicating one of the symbols as a current symbol; a four-directional control device configured to receive commands, the four-directional control device being configured to receive commands associated with a first, second, third and fourth directions; and a controller configured to, based on the received commands, selectively effect the change of the current symbol list to one of the other symbol lists, effect relative movement between the cursor and the current symbol list, and select the current symbol as an input, wherein the controller is configured to effect the change of the current symbol list to one of the other symbol lists in response to commands received when the cursor indicates one of the switch lists symbols and associated with at least one of the directions. - View Dependent Claims (17, 18, 19, 20, 21)

24. A non-transitory computer-readable recording medium having a program recorded thereon that causes a processor of a frequency converter to execute operations comprising:
-
grouping potential symbols into at least two symbol lists; treating one of the symbol lists as a current symbol list; displaying at least part of at least the current symbol list; displaying a cursor indicating one of the symbols in the current symbol list as a current symbol; receiving commands via the four-directional control device; and based on the received commands, selectively changing the current symbol list to one of the other symbol lists, effecting relative movement between the cursor and the current symbol list, and selecting the current symbol as the next symbol in the symbol string.
