Double click on the Symbol button in the object type palette in the Copyist Tools window to open the symbol palettes. Click on the Misc. palette. The Miscellaneous symbols palette will open, showing you all of Copyist's time signature numbers.
Select the first symbol of the time signature you want by clicking on it. (If you are entering a common time or cut time signature you only need one symbol. Otherwise choose the numerator first.) The symbol you choose appears on the Symbol button.
Choose the pencil tool from the toolbar. Now enter the time signature symbol on your page. Do this by clicking and holding down the left mouse button. The time signature symbol will appear at the mouse cursor. As you continue to hold down the left mouse button, you can move the mouse and the symbol will follow, until you have positioned the symbol where you want it on the page. When the symbol is positioned where you want it, lift the left mouse button and the symbol will be placed onto the page.
If you need to enter the time signature denominator to complete your time signature, select it and enter it in its place as you did the numerator.
You can also enter a time signature at the cursor position using keyboard commands. For example, a cut time symbol is entered by pressing C then -, and a 3/4 time signature is entered by moving the cursor until it is centered on the second line of the staff, pressing 3, then moving the cursor down until it is centered on the fourth line of the staff and pressing 4.
You can move or edit the time signature after you have entered it, either by double clicking on each time signature symbol and selecting one of the edit operations from the edit menu that appears, or by dragging the left mouse over the complete time signature, drawing a box around it, lifting up the left mouse button and then selecting one of the edit operations from the edit menu that appears.
