Hello,
In Libreoffice, calc spreadsheet,
how can I enter same data in several cells same row, without using copy ^ paste about 70 or more times.
Answers will be appreciated.
Thanks

If the “several cells” are selected as a single cell range (and the focus cell, the one with the border, isn’t an unselected cell outside), simply type or paste-in your new content and hit Alt+Enter.
If the selection is multi-range this won’t work, but with multiple selected sheets it does…

for ref. from Shortcut Keys for Spreadsheets :

and if “several cells” are explicitely referencing a main one, then one input will show up everywhere.
