Hi, The docs say this about S-M + arrow keys on clock log lines. (In section: 8.4.1 - Dates and Times > Clocking Work Time > Clocking Commands)
‘S-M-<UP>’ (‘org-timestamp-up’) ‘S-M-<DOWN>’ (‘org-timestamp-down’) On ‘CLOCK’ log lines, increase/decrease the timestamp at point and the one of the previous, or the next, clock timestamp by the same duration. For example, if you hit ‘S-M-<UP>’ to increase a clocked-out timestamp by five minutes, then the clocked-in timestamp of the next clock is increased by five minutes. But it doesn't seem to work like that. For example * Testing it out :LOGBOOK: CLOCK: [2023-02-07 Tue 12:35]--[2023-02-07 Tue 12:45] => 0:10 CLOCK: [2023-02-07 Tue 12:20]--[2023-02-07 Tue 12:30] => 0:10 CLOCK: [2023-02-06 Mon 12:20]--[2023-02-06 Mon 13:20] => 1:00 :END: If I put point on the minutes of 12:30 (second line) and hit S-M-<UP>, it moves the time to 12:35, but nothing else moves. Based on the docs, I thought it would shift one of the other lines.
