To enter a value, or a string of text

There is a single all-purpose input field in the upper half of the window beneath the tab: T-table.

If you are instructed, say, to enter $2

  • click the input field and alter its contents to read: $2
  • press Enter.

If you are instructed, say, to change the value of line {1} to 98.7

  • select line {1}
    the entire line {1} becomes hilit, and its value appears in the input field
  • click the input field and alter its contents to read: 98.7
  • press Enter.

To clear the input field (prior to typing new contents),

  1. double-click it
    the entire text within it becomes hilit
  2. press the Backspace key [<--]

To change the unit of selected line, type [unit].

To change the description text of selected line, type 'string.

Another way to alter the value of a line

When building a t-table, a useful trick is to increase or decrease a given value by a small percentage. This gives you a feel for how sensitive a calculation is to its inputs.

If you are instructed, say, to increase the value of line {1} by 1%

Other tools to increase or decrease the value of a given line are:

To change a line to zero, 1 or -1

0 and 1 are frequently encountered target values, so there are special tools to change the selected line to 0 or 1 with a single click…

  • setv0 (a black "0")
  • set1u (a black "1" preceded by a red minus sign)

The red part of a tool icon represents a direction or an extra feature you get with shift-click.
