=== Searching for Blocks ===
  
The Library contains the different blocks installed in the GRC block paths. Here we find blocks that are preinstalled in GNU Radio and blocks that are installed on the system. At first it seems daunting to look for blocks. For instance, if we want to generate a waveform, what category should we look in? We see there is a '''Waveform Generators''' category, okay not bad. But what if we wanted to find some way to display our data but aren't sure of the best way to display it yet? We know from [[Guided_Tutorial_Introduction|A brief introduction to GNU Radio, SDR, and DSP]] that this is known as a sink; however, looking through the list there is no Sinks category. The solution is to use the Search feature by either clicking the magnifying glass icon or typing Ctrl+f and then start typing a keyword to identify the block. We see a white box appear at the top of the Library with a cursor. If we type &quot;sink&quot;, we can find all the blocks that contain the words &quot;sink&quot; and the <span style="color:blue">categories</span> where we will find each block.
