### Sender address line

First of all, we will create the sender address line in the address area. This line will be positioned so as to be seen in window envelopes.

- Select the text tool in the Toolbox panel.

- Now click somewhere in the letter document and create a frame by dragging a rectangular frame. Your document may then look like this:

- Now open the Geometry inspector, and adjust the measurements of the created frame to be the same as those shown in the next figure: X 2.0cm, Y 4.5cm, W 8.5cm, H 0.5cm.

- Now zoom to the text frame to allow easier text editing. Therefore choose Zoom to Selection in the View menu. Your document should now look like this:

- Please enter your postal address in the text frame, similar to that shown in the following example. Because the current tool is still the text tool, you can simply type into the selected frame. You will always recognize a selected frame in text edit mode by at least one visible text ruler above the frame. Your postal address will probably not fit completely into the text frame:

  Can you guess what's coming next? – Right, we should re-define the font size for this text frame as it is currently too large.

- Select the whole text in the frame by choosing Select All in the Edit menu. (Alternatively, you can press [Command][A] — you will become familiar with the menu short cuts by and by.) The text is selected now (indicated by being highlighted in blue):

- Now open the Text inspector and have a look at its parameters:

  Your Text inspector will probably show similar values.

- Change the font size for the selected text. Therefore, click into the edit field Font size and enter the value 7. There is no need to enter 7.0000pt or 7.0. iCalamus will format the value automatically. You may also decrease the value with the [Down Arrow] key on your keyboard in steps of 0.1pt, or with [Shift][Down Arrow] for full unit steps.
  Now your document should look like this image:

- Please complete your address text. When you are done, your text frame should look like this one:

- We believe that the sender address text should be centered in the frame, don't you? No problem, just open the Text Ruler inspector:

- There you find a list for text rulers which currently only contains the default ruler. Don't touch it, but click on the [+] button to create a new text ruler.

- Adjust the new text ruler parameters as shown in the next figure. When you close the dialog with [OK], the new ruler will be inserted in the text ruler list, and it will be used in your text frame automatically.

- Your sender address line text frame is done for now. Choose Deselect All in the Edit menu to deselect the text frame.

- Your document should now look similar to the following image:
