Typing big operators

The following key-combinations are used in order to create big symbols:

Shortcut Result Shortcut Result
S-F5 I ∫ S-F5 O ∮
S-F5 P ∏ S-F5 A ⨿
S-F5 S ∑ S-F5 @ + oplus
S-F5 @ x otimes S-F5 @ . odot
S-F5 U cup S-F5 N cap
S-F5 V vee S-F5 W wedge

Table 1. Big mathematical operators.

The big integral signs admit two variants, depending on where you want to place subscripts and superscripts. By default, the scripts are placed as follows:

∫
∞
0
ⅆ x
1 + x2
.

The alternative rendering “with limits”

intlim
∞
0
ⅆ x
1 + x2
.

is obtained using S-F5 L I. Similarly, you may type S-F5 L O in order to obtain ∮ with limits.
