alphanumeric entries such as function and variable names. These tips may make alpha entry more
efficient.
! Learn the keyboard. While this seems obvious, some users become quite proficient.
! Use [CUT], [COPY] and [PASTE] to reenter variable and function names.
! Use the [MATH] and [CATALOG] menus to enter function names. Use [F4] in the CATALOG
display to enter user function and program names. Variable and function names can also be
entered from the VAR-LINK menu.
! Use [ANS], as well as [UP], [DOWN] and [ENTER] to retrieve entries and answers from the history
display, then edit them in the command line.
! Use simple variable names, especially those with "x", "y", "z" and "t". Remember, though, that y1 -
y99, z1 - z99 and t0 are reserved system variable names and cannot be used.
! Take advantage of the custom toolbar menus. The default toolbar menu set includes many common
commands, but using your own menus, with the commands you frequently need, will save even
more time. Refer to other tips for ways to enhance custom menus.
! Consider assigning shifted-key characters to custom toolbar menu items. For example " and " is
useful with solve(). You may even want to make menu entries for "{}" and "[]" to speed list and
matrix entry.
! Remember that you can have up to nine 'keyboard programs' which are executed with [DIAMOND]
[1] to [DIAMOND] [9]. These are particularly effective when each keyboard program is assigned to a
different custom toolbar menu.
! Some users prefer to hold [alpha] while typing characters. This can be more convenient than using
the alpha-lock ([a-lock]) key.
