Here are some selected office application how-tos for myself. See also: Office Application Settings, Programs.
Parts of a spreadsheet document
cell = an intersection of a column and a row, for example cell A1
column = vertical group of cells
row = horizontal group of cells
worksheet (sheet, tab) = like a physical sheeting, contains one or more columns and rows
spreadsheet (or workbook) = a file containing one or more worksheets
Absolute reference
$A1 = column A locked, row can change
$B$2 = column B locked, row 2 locked
Fill Handle
Make cell A1 = 1, make cell A2 = 2, and then drag down the black fill handle
Refer to cells in other cells
A1;A13;D7 (refer to certain cells, one at a time, separated by semicolon)
B1:B10 (refer to an area (group) of cells, separate top left and bottom right cell with a colon)
Information type
use ' (apostrophe) as the first character in a cell to define cell's contents as text
Formula
use = (equal sign) as the first character in a cell to define the contents of the cell as a formula
Functions
SUM(A1:A3) = sum of cells A1, A2, and A3
IF(condition; value1 if condition true; value2 if condition false)
AND(argument1; argument2; ...; argument30)
Nested (embedded) functions
IF(AND(A1>10;B2>100;C3>1000);"SUCCESS";"FAIL") = if 3 cells contain high enough values, it's a success
Conditional Formatting
LibreOffice Calc: Format: Conditional Formatting: Condition
[Cell value is] [less than] [100]
[Apply Style] [Red text]
Sort data
LibreOffice Calc: select area of cells, Data: Sort
Automatic filtering ("sort"/"hide")
LibreOffice Calc: select header row (e.g. cells A1..A10), Data: Filter: Autofilter
Chart (graph): create
LibreOffice Calc: select a group of cells, Insert: Object: Chart
Chart: edit color, font, etc.
LibreOffice Calc: click once on the chart to select it, then double-click part of the chart, then click the section you want to modify
