THINK IN PAGES, NOT SCROLL
Each Teletext Tools page should fit inside the frame. If information grows, it becomes another internal screen or another numbered page.
DENSITY IS A FEATURE
The design is intentionally compact. It helps you scan choices quickly once you know the page-number system.
IF IT DOESN’T FIT
Correct fix: split into more screens. Wrong fix: hide content behind the footer or shrink text too far.
BEST START
Use P101 for the master directory and P199 for the full index.
TYPE PAGE NUMBERS DIRECTLY
Typing 101, 199, 201 or 500 is faster than browsing menus.
USE THE INDEX AS A TELEPORT
P199 is the safest route when you know the topic but not the exact page number.
USE NEARBY PAGES
Tools in the same section usually sit near each other. Use PREVIOUS and NEXT for neighbouring pages.
CORRECTING A MISTYPE
Just keep typing the correct three digits. The page box is built for quick replacement.
PAGES VS SCREENS
A page number changes the Teletext page. NEXT and PREVIOUS inside the frame change screens within the current page.
WHEN TO SWIPE
Swipe left or right for internal screens only. Use the PAGE box for a new numbered page.
READ THE COUNTER
Labels such as 1/4 or 2/4 show how much internal content exists.
KEYBOARD SHORTCUT
On laptop or desktop, use the left and right arrow keys to move through internal screens.
CHECK FROM / TO FIRST
Most wrong-looking results are swapped units. Check the unit labels before changing the value.
USE SMALLER UNITS
Convert metres to millimetres, kilograms to grams, or litres to millilitres when you want cleaner everyday numbers.
PRESETS AS TEMPLATES
Presets are starting points. They fill sensible values, but you can change them freely.
UNIT FINDER
Use P201 when you know the unit but do not know which converter category it belongs to.
FORMATTING VS MATHS
Display formatting is for readability. It does not change the underlying conversion or calculation logic.
TRAILING ZEROS
Trailing zeros are removed to keep the Teletext frame readable and compact.
SCIENTIFIC NOTATION
Scientific notation appears only when it helps with very large or very small values.
NEED MORE DETAIL?
Choose a smaller unit or use a more suitable tool if you need extra precision.
WAIT AFTER A SWIPE
A short swipe guard prevents accidental ghost taps on touch devices.
DISMISS KEYBOARDS
Tap outside an input to close the keyboard and reveal the page frame again.
ROTATE IF NEEDED
Portrait is usually best for forms. Landscape can help clocks, displays and visual tools.
NO PAGE SCROLL
If content feels hidden, use internal NEXT/PREVIOUS instead of trying to scroll.
USE LANDSCAPE MODE
Landscape often gives the clearest wall display for clocks, timers and screensavers.
KEEP CONTRAST HIGH
Dark, simple backgrounds usually work best behind Teletext colours.
PREVENT SCREEN SLEEP
Use your device display settings for long-running classroom, desk or wall displays.
TIME SECTION
Use P300 for the time and clock home page.
NO ACCOUNT NEEDED
Teletext Tools is designed to work without a login for everyday use.
SAVED SETTINGS
Some tools remember choices locally on your device for speed.
PRIVATE BROWSING
Private browsing or clearing browser data may reset saved preferences.
MULTIPLE DEVICES
Settings usually do not sync between devices unless a page uses shareable URL options.
MOST ROWS ARE TAPPABLE
If a row shows a page number or tool name, it is usually safe to tap.
COLOUR MEANING
Yellow often highlights navigation or emphasis. Cyan usually marks supporting information.
RIGID BY DESIGN
Predictability matters more than fancy animation. The frame should feel stable.
SECTION MEMORY
Learn the page ranges: 300 time, 400 random, 500 printable, 600 calculators, 700 converters, 800 arcade.
