This can be very helpful for laptop users and can speed up certain operations. **Activating the Command Bar** The default command bar state can be controlled using the **Options > Command Bar** menu option, click the **Command Bar** option to toggle on. Options > Command Bar Regardless of the visibility of the command bar you can always activate it and prepare it for input using the keyboard shortcuts as follows: **Alt + C** – Show the command bar. And set focus to it (make it ready to receive keyboard input). **Shift + Alt + C** – Hide the command bar. Using these key combinations does not change the default state. It simply changes the immediate availability state of the command bar. **Using the Command Bar** The command bar allows you to do the following: 1) Perform any menu operation on the main menu 2) Select element(s) from the model 3) Change attribute values on the currently selected element(s) 4) Perform operations on the currently selected element **Basics** As you type in the command bar the system will show possible commands or options that match the partial command or option you have entered up to that point. To select one of the suggestions, use the **up or down arrow** to highlight the desired item and then press the **Tab** key. The highlighted suggestion will be placed in the correct spot on the command bar. Begin to type a word command Press the **?** button to see the complete list of available commands. Pressing the **Esc** key clears the entire command bar. Pressing **Alt + Backspace** keys deletes the options but leaves the command in place. **Menu Operation** To activate a menu command, enter “**Command**”, “**Cmd**”, or “**Menu**” or a portion there of and press Tab. The auto complete list then presents a suggested list of commands matching your entered filter value. Menu commands Press **Tab** to highlight the desired option (or simply type the entire value minus the portion in parenthesis). To Execute the menu operations on the Inventory pane enter “**Inv**” instead of “Menu”. Once a valid command option has been entered pressing **Enter** performs that menu operation. In all menu operations you can traverse any resulting dialogs using **Tab** and **Shift + Tab**, entering desired values, and then press** Enter** to execute the operation or **Esc** to cancel. Typically, the **Ctrl** key will return to the command bar, but on those occasions when it does not simply press **Alt + C** to return to the command bar. **Selecting Elements** To select elements, enter the command “**Select**” into the command bar and press **Tab**.  Focus then transfers to the inventory tree.   1) Traverse the tree using the up and down arrows.   2) Expand or collapse items in the tree using right or left arrows.   3) Holding shift allows you to select multiple items.   When your selection is complete press **Enter** to return to the command bar. Select command **Changing Values** To change an attribute value, enter the command “**Set**” or “**Val**”, select the attribute name to be changed and then press = and the same edit box or list that comes up in the **DEP **will be displayed inline in the command bar. All the same operation commands (**Tip-**, calculator, Ind, f’I”, abs, etc.) that you are used to using in the DEP are available in the command bar. Set or Value command **Context Menu** The context menu operation for the selected element (there must be only one element selected) is activated by pressing the **Menu** key on the keyboard.  The same menu that comes up when you right click on an element in the Inventory or in 3D view displays in the command bar window. Menu command **Setting the DEP (Data Entry Panel) Filter** To change the filter option of the currently selected DEP panel enter the command “**Filter**” and press **Tab** and select the desired filter. Filter command **Selecting Charts and Reports** To select the displayed chart or report enter “**Chart**” or “**Report**” press **Tab** and select the desired chart or report from the displayed list.   Chart command Remember that the selected pole model must be currently calculated (see the **% of Allowed MCU** result in the **Capacity** display) to display Chart or Report results.
