Yahoo Finance Freecashflow and Operating Cashflow

I want now to clarify the definition for Operating Cashflow and Levered Free Cashflow found on Yahoo finance. What are they?

By Operating Cashflow do they indicate the Cashflow from Operations line found on the Cashflow Statement? The Cashflow from Operation line is arrived by starting with net income and subtracting a bunch of items from it, and adding a bunch of items one of which is the (adding back of) the SBC. Is that correct?

Levered Free Cahsflow is the same as Free Cashflow to Equity (FCFE). Do they start with the cashflow statement’s line Cashflow from Operations (defined above), and subtract the SBC from it ( -Capex+debt issuance=FCFE )?
