In Version: 5.4.0.3 (x64) Build ID: 7556cbc6811c9d992f4064ab9287069087d7f62c CPU threads: 4; OS: Windows 6.19; UI render: default; Locale: en-GB (en_GB); Calc: group under Windows 10 CNTL+D does nothing even when set to the default action in Calc Fill Down. Sheet->Fill Cells->Down works Assigning CNTL+F to Fill Down in Tools->Preferences... works. Other keyboard shortcuts appear to work. Deleting the default CNTL+D action, then restoring it also fails. CNTL+D worked in previous versions. I have tried this with two different keyboards.
Work for me with the same build. Version: 5.4.0.3 (x64) Build ID: 7556cbc6811c9d992f4064ab9287069087d7f62c CPU threads: 4; OS: Windows 6.19; UI render: GL; Locale: es-ES (es_ES); Calc: group
Have you checked this shortcut hasn't be customized? To be sure, you can rename your LO directory profile (see https://wiki.documentfoundation.org/UserProfile#Windows) and give a new try.
Oups forget my check suggestion, it seems I read your description too quickly. Sorry for the noise.
I cannot confirm with Version: 6.0.0.0.alpha0+ Build ID: b032f21b5ea0011f2b134d758b696604c18dfa16 CPU threads: 1; OS: Windows 6.1; UI render: default; TinderBox: Win-x86@42, Branch:master, Time: 2017-08-04_23:35:39
Works for me. The only difference in the version info is en-GB. Win 10 Version: 5.4.0.3 (x64) Build ID: 7556cbc6811c9d992f4064ab9287069087d7f62c CPU threads: 4; OS: Windows 6.19; UI render: default; Locale: fi-FI (fi_FI); Calc: group
Now works for me. It has suddenly started working again for me. I don't know why. There are reports going back to 2005 of an identical bug with Excel. I have found no convincing explanation in these bug reports. The consensus seems to be that some other application is grabbing CNTL-D. But the error seemed to persist in safe mode.
Let's put this one to WFM then.
