• It is, nevertheless, possible to draw the curved arrows for a sequence of discrete electron transfers that give the same result as a rearrangement reaction, although these are not necessarily realistic.
• In general the stepwise progression of reaction mechanisms can be represented using arrow pushing techniques in which curved arrows are used to track the movement of electrons as starting materials transition to intermediates and products.
• The stepwise course of any given reaction mechanism can be represented using arrow pushing techniques in which curved arrows are used to track the movement of electrons as starting materials transition through intermediates to final products.
• When a bond is broken, electrons leave where the bond was and this is represented by a curved arrow pointing away from the bond and ending the arrow pointing towards the next unoccupied molecular orbital.

• As well as some interesting oddities, such as the domestic " stay left " signage ( black left-upward curved arrow in red circle ) occasionally used instead of the now more common British sign ( white left-downward straight arrow on blue disc ).
• Some domestic signs were also invented, such as the keep-left sign ( a black curved arrow pointing to the upper-left, although some are similar to the European " white arrow on blue disk " signs ), while some other signs are not widely adopted outside Ireland, such as the no-entry sign ( a black arrow pointing ahead in a white circle with a red slashed circumference ).
• A long straight arrow indicates movement from the elbow, a short arrow with a cross bar behind it indicates motion from the wrist, and a simple short arrow indicates a small movement .

( Doubled, in opposite directions, these can show shaking of the hand . ) Arrows can turn, curve, zigzag, and loop-the-loop.
