@iitgrad - see: Command Palete doesn't show local build/flash options - #4 by m_m
TL;DR
The
Ctrl/Cmd
+Shift
+B
shortcut will only show you Build tasks (we have both "Build" and "Clean" tasks)
Click the “Terminal” menu, then selecting “Run Task…” while you have your Particle Workspace open ("File" menu then "Open Workspace") will show all the available tasks.
