For some types of files, you can use the code folding feature to collapse blocks of code so that only the first line of the block appears in the Source Editor.
In the Quote_1 application project, open the Source Files folder, then double-click the cpu.cc file to open it in the Source Editor.
Click the collapse icon (small box with minus sign) in the left margin to fold the code of one of the methods.
Mouse over the {...} symbol to the right of the folded block to display the code in the block.
