[5] After the execution of Charles I in 1649 he was appointed the junior of the three Lord Commissioners (along with Bulstrode Whitelocke and John Lisle) who had the custody of the Great Seal, they each having a salary of £1000 per annum.
[2][6] With William Lenthall, acting as the Master of the Rolls, Keble and Whitelocke issued a set of working rules for the Court of Chancery, while further reform was being deliberated.
[7] Keble presided at two significant trials: that of John Lilburne the Leveller in October 1649, and that of the Presbyterian plotter Christopher Love in 1651.
[11] At the Restoration Keble was excepted from the Indemnity and Oblivion Act (under Section XLIII which forbade him from accepting a public office).
[12] Hilkiah Bedford, a political opponent, called him "an insolent, mercenary pettifogger," who without jury or evidence sent to the gallows any he suspected of royalism.
